Laboratory Thermometers for Accurate Temperature Measurement

Laboratory Thermometer Models are used to monitor temperature during concrete, asphalt, material testing and general laboratory procedures. Temperature can directly influence test conditions and material behaviour, making the correct measuring instrument an important part of laboratory work.

Liya Test offers a broad selection including digital thermometers, glass thermometers, infrared thermometers and K-type thermocouple compatible multi-channel models.

Digital Thermometer Options

The LT-G0185 Digital Thermometer operates from -50 to +300 °C and provides a general-purpose solution for laboratory temperature measurement.

The LT-G0186 Digital Max-Min Thermometer covers -50 to +70 °C and includes a 50 cm measuring cable. This arrangement allows the sensor to be positioned separately from the display unit.

The product group also includes the LT-G0187 Max-Min Thermo-Hygrometer for temperature monitoring in suitable laboratory environments.

Infrared Temperature Measurement

The LT-G0188 Infrared Thermometer provides non-contact temperature measurement over a range of -50 to +380 °C.

Infrared measurement is useful when direct probe contact is inconvenient or when a quick surface temperature check is required.

Because infrared thermometers primarily measure surface temperature, the selected method should match the actual laboratory requirement.

Glass Thermometer Models

Traditional glass thermometers are also included in the product range.

The LT-G0182 model is listed with a maximum temperature of 110 °C, while the LT-G0183 model reaches 360 °C.

These models provide a simple analogue alternative for suitable laboratory procedures where electronic measurement is not required.

K-Type Thermocouple Thermometers

For applications requiring wider temperature ranges, Liya Test offers thermocouple-based digital instruments.

The LT-G0290 is a 1-channel model covering -50 to +1300 °C.

The LT-G0291 extends the range to -200 to +1300 °C, while the LT-G0292 provides the same range with 2-channel measurement.

For monitoring several points, the LT-G0293 4-channel thermometer allows multiple thermocouple inputs to be used within a single measuring unit.

Concrete and Asphalt Applications

Temperature monitoring can be important during concrete and asphalt testing.

In concrete applications, thermometers may be used to follow temperature changes during curing or other test procedures.

For asphalt and bituminous mixtures, temperature measurement can support material preparation, delivery and compaction-related checks.

The appropriate sensor type and measuring range should be selected according to the actual test method.

Thermocouple Accessories

The product group also includes the LT-G0295/1 K-Type Thermocouple Cable and LT-G0295/2 Thermocouple Socket.

These accessories support the connection of suitable K-type thermocouples to compatible measuring instruments.

Cable length and sensor arrangement can be selected according to the measuring point and laboratory setup.

Selecting the Correct Thermometer

The correct thermometer depends on several factors:

• required temperature range
• contact or non-contact measurement
• number of measurement points
• required resolution
• laboratory or field use
• probe and cable arrangement
• test method requirements

For basic temperature monitoring, a standard digital or glass thermometer may be sufficient. For wide temperature ranges or several simultaneous measuring points, a thermocouple-based system may be more suitable.

Overall, the Laboratory Thermometer range provides solutions from simple analogue measurements to 4-channel K-type thermocouple monitoring up to 1300 °C, supporting concrete, asphalt and general laboratory applications.
