ETI 860-840 Standard Bluetooth Legionella Thermometer Kit

ETI 860-840 Standard Bluetooth Legionella Thermometer Kit helps users take clear, time-stamped readings for Legionella risk checks. It sends results to a phone or tablet with a single tap, which helps reduce paper records. Two probes are supplied, so users can complete different checks with one kit.

This water thermometer kit uses Bluetooth BLE 5.0 to link with compatible devices. It works with the ThermaData Hub app and software, which supports custom checklists, result review and data export. As a result, site teams can store readings with less admin.

Fast Digital Recording

ETI 860-840 Standard Bluetooth Legionella Thermometer Kit measures across a wide thermocouple range. It can read from -199.9 to 299.9 °C at 0.1 °C resolution and from 300 to 1372 °C at 1 °C resolution. This makes it suitable for water checks and wider K-type probe tasks.

Readings are accurate to ±0.4 °C plus 0.1% of reading for the instrument only. A free traceable calibration certificate is included, so users can trust the supplied measurement data. The kit also includes max and min functions for simple result review.

Made for Regular Site Use

Built in Britain, the ETI 860-840 Standard Bluetooth Legionella Thermometer Kit has an ABS plastic case with Biomaster product protection. Its 12 mm LCD gives clear on-site readings. The compact body weighs 140 g and measures 25 x 56 x 128 mm.

A long 3000 hour battery life supports routine use across many visits. Auto power off after 10 minutes helps extend battery life. Two different set types are available, giving users a choice of kit options for their work.
