Water Temperature

Swimming Pools & Bathing Facilities

Position the waterproof probe at the water measuring point and place the display where staff can check it during routine inspections. Keep the screen, adapter and electrical connections dry and protected from splashes.

External Probe

Fish Tanks & Water Tanks

Use the 5 m probe cable to separate the measuring point from the viewing position. Mount the screen on a suitable nearby wall so temperature readings are convenient to check during feeding, maintenance or daily rounds.

Installation Planning

Sauna Temperature Measurement

An external probe allows the measuring point and display to be positioned separately. Tell us the expected temperature and whether the location is dry or exposed to steam, so we can confirm suitability. The probe's measuring range does not mean the display can be installed in the same high-temperature environment.

Frequently Asked Questions

Find answers about temperature units, the external probe and installation requirements.

Can LX923TM switch between Celsius and Fahrenheit?

Yes. LX923TM lets you select Celsius (°C) or Fahrenheit (°F). It displays one temperature reading in the selected unit, with the unit indicator beside the digits.

Does this configuration include an external probe?

Yes. The configuration offered on this page uses an external waterproof temperature probe with a standard 5 m cable. The temperature is measured at the probe, allowing the display to be mounted at a separate viewing location.

Can I use it to measure pool or fish tank water temperature?

The external waterproof probe can be used for water-temperature measurement in applications such as swimming pools and fish tanks. Position the probe at the measuring point and keep the display, power adapter and electrical connections dry and protected from splashes.

For saltwater, chemically treated water or other potentially corrosive liquids, tell us the medium so we can confirm probe material suitability.

Can the display be installed inside a sauna?

The probe's measuring range does not establish the display unit's suitability for high ambient temperatures or steam. Describe the sauna temperature, moisture conditions and planned mounting positions so we can confirm the installation requirements before you order.

Can I order a different probe cable length?

The standard cable length is 5 m. If your installation needs a different length, include the required cable length and measuring application in your inquiry. We will check the available configuration before confirming your order.

How is LX923TM mounted and powered?

LX923TM has rear slots for wall mounting and operates from a 5V DC power adapter. Choose a dry, visible mounting location with access to power and a suitable cable route to the probe. Tell us the delivery country so we can confirm the adapter plug for your order.
