One probe or two
TES-21 reads a single probe and TES-22 reads two, each on its own channel, from one battery-powered sensor.
Probe Temperature Sensor
TES-2X
Battery-powered wireless probes for pipes, cold stores and equipment, accurate to ±0.2 °C across the normal range. One probe or two, in the style and cable length the job needs, for up to ten years on one cell.

Works with the Gateway
Features
10 yr battery life at 15-minute reporting
Up to ten years from one user-replaceable lithium cell, estimated at 23 °C with full wireless coverage.
A probe for each job
Every probe uses a 10k NTC thermistor.
- Short waterproof probe
- Waterproof probe, 1.5 m
- Waterproof probe, 2.5 m
- Steel pipe probe, 2 m
- Steel general-purpose probe, 2 m
±0.2 °C accuracy across the normal range
0.01 °C resolution, and ±0.5 °C across the full −40 °C to 105 °C range.
Sealed from probe to case
IP68 probes and an IP67 polycarbonate enclosure, rated to operate from −30 °C to 55 °C.
Nothing lost in a radio outage
Up to 70,000 readings are kept in flash on the sensor, time-stamped, and sent when the link returns.

Guides
Engineering tools
Used in
-
Cold room and cold store temperature monitoring
Probes at the warm and cold points a mapping study found, one in the product zone, and alarms that carry a delay so a door opening is not an incident. -
Legionella temperature monitoring
Wireless pipe probes on the calorifier flow and return, the end of each loop and the cold feed. Edge trends every point and raises an alarm when a temperature drops or a sensor goes quiet. -
Indoor environmental monitoring
A probe where people actually are, an outdoor reference to compare it with, and the ventilation state that explains the difference. -
Server room and rack temperature monitoring
Probes at the rack inlet and exhaust, a separate humidity transmitter, and each point’s position, history and alarms kept together in Edge. -
Refrigeration demand response
Probes in the product zone can veto an event. A representative site trial sets the permitted duration, and plant protection stays independent of the controller. -
Transformer and distribution board monitoring
A meter at the incomer, meters on the feeders worth explaining, and a temperature probe where loading has to be read against heat.

Questions engineers ask
Which probe should I choose?
Which probe should I choose?
The waterproof TPE probes suit air and liquids in cold rooms, fridges and tanks, on a short lead or a 1.5 m or 2.5 m cable. The pipe probe has a flattened stainless tip that sits against a pipe, for flow and return or hot-water checks. The steel general-purpose probe has a stainless cap for places where a metal probe is preferred.
How accurate is it?
How accurate is it?
±0.2 °C across the normal range (−20 °C to 70 °C for the waterproof probe, 0 °C to 70 °C for the steel probes) and ±0.5 °C across the full −40 °C to 105 °C range, at 0.01 °C resolution.
How long does the battery last?
How long does the battery last?
Up to ten years at 15-minute reporting, estimated at 23 °C with full wireless coverage. A shorter interval, a colder site or a weak signal shortens it. The A-size lithium cell is replaced by the user.
What happens if the radio link drops?
What happens if the radio link drops?
The sensor keeps measuring and holds up to 70,000 readings in flash, so the record has no gap when the link comes back.
Can I get a calibration certificate?
Can I get a calibration certificate?
Yes. Each probe can be calibrated by EpiSensor at one point, or to UKAS at three points (0 °C, 5 °C and 10 °C by default). Ask us when you order.
Does a TES work on its own?
Does a TES work on its own?
It reports to a ZGW-20 Gateway, which stores the readings, raises alarms in Edge and sends the data on to your platform.
