The RF312 Glycol Simulant WiFi Data Logger (with detachable buffer probe) is designed specifically for use in monitoring the temperature of perishable items, such as food, samples and vaccines.
The high accuracy data logger is typically accurate to ±0.2°C* (-15°C to +80°C) / ±0.4°F (+5°F to +176°F). Data is streamed wirelessly over any WiFi network and can be viewed from anywhere, using the Comark Cloud. (*Using the supplied Glycol Probe)
The Glycol Buffer Probe RFAXGlycol is designed to provide a buffered response to changes in temperature. This helps to simulate the thermal lag experienced by products stored in the monitored environment.
Data is transmitted wirelessly via your WiFi network to the Comark Cloud.
The Comark Cloud Dashboard is your new online Home for your Loggers and provides easy access to the critical information regards your system, including; the status of your favourite devices at a glance, review recent device events, view data and clear alerts, quickly navigate to the detail on all your devices.
Simply log on to the Comark Cloud Dashboard via your PC, Tablet or Phone.
You must first Register with Comark and Create a Cloud Account via their website you will find the link below. You may then setup your loggers quickly and easily with the free with the App (Recommended) or PC software.

Note: The Glycol probe supplied is compatible with this logger and the RF312DUALPLUS, it is not compatible with the RF312-TP logger. If you require an Air probe for use with this logger, please see the Related Products section below.This logger is compatible with the regular RFAXxxxJ probes with the following accuracy specifications ±0.3°C (0°C to +70°C) / ±0.6°F (+32°F to +158°F).
If the data logger temporarily loses connectivity with the network, it will log readings until the connection is re-established (max 30 days at 10 second sample interval).
Although the Diligence WiFi data loggers have an impressive range this can be increased by using WiFi extenders.
The RF312Glycol Diligence WiFi Glycol Simulant Data Logger with a GLYCOL Probe, is a low power device containing a rechargeable battery. When configured, the data logger can operate for up to six months*. The battery can be recharged via a standard +5V wall adapter RF320 (UK/US) or a USB port using the cable provided.
The LCD display includes several features including Max and Min readings and indicators for low battery, alarms, WiFi connection and signal strength. The RF312GLYCOL has a protection rating of IP42 and the glycol probe, IP67. The RF312GLYCOL is freestanding, but can be attached to a wall or surface using the bracket provided. The glycol buffer probe is supplied with a detachable magnetic base for easy installation.
From the Comark Cloud Dashboard you can change the data logger’s settings to suit your needs, options include;
- Assigning names to the data logger and each measuring channel
- Selecting the units of measurement
- Choosing the sample rate and transmission period
- Setting high and low alarm levels for each channel
- Manage Users and Locations
Enjoy an Audit Trail, with detailed reporting, data exporting and notification options, including e-mails and SMS**
The RF312Glycol has a protection rating of IP40 and the probes IP67. The data logger is IEEE 802.11b/g/n compliant, supports WEP, WPA/WPA2 encryption and enterprise networks***.

Battery Life and Power Supply.
The product will arrive partly charged, but ideally you should charge it for 24 hours before use for optimum performance. The battery can be recharged (unit must be between 0°C to +40°C / +32°F to 104°F) via a PC, a USB +5V wall adapter RF320 (UK/US), or a portable USB battery pack using the USB lead provided. It can also be permanently powered by the RF320 USB wall adapter. Readings may be affected while the internal battery is being charged. However, once charged, continued connection of the charger will have no effect.
Battery life is dependent on: transmission period, WiFi encryption method, WiFi encryption key rotation frequency (determined by the router/access point), signal strength between router/access point and WiFi device, presence volume and type of WiFi traffic from other devices, sample rate and operating temperature.
