RF500
Wireless monitoring system
This system provides effortless 24/7 monitoring of temperature, humidity and door events. Low power RF technology with built-in mesh networking, and transmitters with bi-directional communications offer:
• Accurate, tamper-proof records
• Secure multi-user access to data via the internet at any time
• Alarm notification via email, phone or sms
• Transmitters that are waterproof and accurate with long battery life
• Compliance with legislative and regulatory requirements
• Plus, it’s easy to install, use and maintain
Manual checks on temperature and humidity are a thing of the past.
The RF500A employs a system of remote sensors and probes to automatically collect and transmit data to a Gateway unit which manages the system and stores the data.
The RF500A Gateway requires no specialist PC software. It connects directly to the local area network permitting 24/7 single or multi-user access via the internet at any time. The system provides a full audit trail, electronic signatures and data protection to meet the requirements of 21
CFR Part 11.
In the event of readings falling outside pre-set limits, alarm notification via screens, SMS, email or voice contact you immediately, so immediate corrective action can be taken.
Advanced features include:
ADR – Automatic Data Retrieval.
In the event of a power failure, data is stored in the RF500A transmitter then automatically transmitted to the Gateway as soon as the network is restored, so no data is lost.
Mesh Network – established through powered transmitters.
This enables the system to automatically adjust to any changes in the environment, rerouting signals as required to ensure that the data is always returned to the Gateway.
Waterproof Transmitters with LCD
Transmitters are fully waterproof and include an LCD for instant data display and an LED for local alarm indication.
Low battery indicator on each unit is viewable via the web. Choose either a model with a 2 year battery life or AC power transformer.

An audible alarm provides an alert whenever temperatures fall out of range of preset conditions so corrective action can be taken before valuable stock is put at risk.
As soon as the Diligence WiFi network is set up, temperature or humidity is continually logged and data is transmitted wirelessly via your existing WiFi network to a PC and viewed using the free Diligence WiFi secure software package. When installed the software allows set-up, data logging and data review. Historic data can be viewed via the graphing tool or exported to Excel.
Use Diligence WiFi Loggers to monitor areas such as walk-in and reach-in refrigerators and freezers, cold storage areas, blast chillers, and hot holding cabinets.

Calibration Instruments
Temperature and measurement instrument performance is vital in almost every application, especially throughout the food industry.
Performance can be affected by many factors including use and abuse and the age of the instrument. Regular, professional calibration checks are recommended, with certification as required, especially for companies with HACCP procedures and other quality systems. In the meantime, calibration can be monitored with
Comark simulators, reference thermometers and validation equipment.

Think how your business could benefit from BioCote
®
protected instruments.
All the latest Comark instruments are manufactured with BioCote
®
antimicrobial technology impregnated into the instrument surfaces, keypads and probe handles.
The technology utilises silver, a natural antimicrobial that helps prevent the growth of bacteria, mould and fungi and lasts for the life of the instrument. When micro-organisms come into contact with a Biocote
® protected surface their growth is inhibited, reducing microbial populations resulting in a more hygenic product.
A trial by BioCote Ltd and The University of
Wolverhampton Science Park canteen was conducted to compare micro-organism levels on a BioCote
®
treated Comark thermometer with an untreated thermometer. The trial was carried out over an 8 week period.
Swabs were taken from the thermometer case, keypad and probe handle before and after each use and the number of contaminating bacteria was counted. The treated instrument showed a dramatic reduction in microbe levels, proving beyond doubt that BioCote
®
protected instruments are significantly cleaner and safer to use in sensitive environments.
The actual result was a massive
92.73% reduction in microbe levels!
Page 27
Temperature Probes
Comark produces one of the largest available ranges of temperature probes, with a probe for almost every application.
Comark can certify temperature probes, either alone, or, as recommended, with an instrument to record system accuracy. Certificates of calibration are supplied through the Comark in-house UKAS accredited temperature calibration laboratory and the in-house NPL traceable laboratory.
The Comark Service Team or your local distributor can offer advice on probes and certification and can provide detailed quotations.

GLOSSARY OF TERMS
ATEX: Atmosphére Explosive. Refers to the current standards for Intrinsically Safe equipment.
Baseefa: Refers to Baseefa 2001 Ltd, the notified body for Comark ATEX compliance.
Differential Measurement: Ability of an instrument to measure temperature, pressure etc. simultaneously from two different points and to calculate the difference between them.
Distance to Spot Size Ratio: The measure of the increase in the target area diameter detected by an infrared thermometer, over the distance from instrument to target surface.
Emissivity: The natural level of infrared radiation from the surface of any material. Emissivity is measured on a scale from 0.1 to 1.0, where 1.0 represents the radiation from a black body.
HACCP: Hazard Analysis and Critical Control Point.
The quality system used throughout the food industry to ensure safe food.
HVAC: Heating, Ventilating and Air Conditioning.
IP Rating: Set of standards for dust and waterproof protection. Many Comark instruments are rated at IP67.
Lumberg: Connector with locking screw, used to provide strong, secure probe-to-instrument connections with better prevention of liquid ingress.
NPL: The National Physical Laboratory.
Operating Range: Temperature and humidity limits within which an instrument will function correctly.
Pt100: Platinum resistance thermometer. High accuracy temperature sensor.
“Quick” Calculations: Pre-programmed calculations available in software, such as average or standard deviation.
Resolution: Indicates the smallest difference in measurements that can be detected and displayed by the instrument, e.g. 0.1° indicates that the instrument can detect differences of one tenth of a degree. In some cases there can be a difference between the detected measurement change and the displayed change.
Sub–miniature: Two-pin industry standard connector.
System Accuracy: Temperature accuracy level for the instrument and probe combined. Instrument accuracy excludes the probe.
Thermistor: Type of temperature sensor offering accuracy suitable for food applications.
Thermocouple: Type of temperature sensor using bi–metal electrical properties. Eight types of bi-metal combinations are available: – K, N, T, J, R, S, E and B – with different measurement ranges and characteristics to suit different applications.
UKAS: The United Kingdom Accreditation Service.
Wraparound: Ability to program a data logger to continue logging when its memory is full, by logging new readings over the oldest readings already in the memory.
