Comark RF312-TP User Manual

RF312-TP Temperature Data Logger
with Probe

The RF312-TP data logger measures the temperature of the
environment in which the probe is situated. Data is transmitted
wirelessly via a WiFi network to a PC and viewed using free software
available to download from www.comarkinstruments.com During
confi guration the data logger will search for an existing wireless
network while physically connected to the PC. It can then be
placed anywhere within range of the network. If the data logger
temporarily loses connectivity with the network, it will log readings
until it is able to communicate again with the PC application (max
120 days at 10 second sample interval). The range of the data
logger can be increased by using WiFi extenders.

The RF314-TP data logger is supplied with a thermistor probe and
can be used with a range of probes from Comark Instruments in
a variety of temperature situations such as walk-in and reach-in
freezers and refrigerators, blast chillers, hot and chilled food storage
cabinets.

The RF314-TC is a low powered battery device with a battery life of
3 months to one year, depending on transmission rate. The battery
can be recharged via a PC or by mains power using the RF320*

power supply unit, which is available as an accessory.
