Accurate temperature measurement is essential for maintaining product quality, process efficiency, regulatory compliance and operational safety in industrial processes. High performance, stable temperature sources are the solution for achieving optimal performance of temperature sensors and process instrumentation, by providing reference temperatures for checking and calibrating these devices. The GE Druck LIQUIDTC-255 Series Liquid Bath Temperature Calibrator provide solutions for testing temperature devices over a range of temperatures from -35°C to 650°C (-30°F to 1200°F). The GE Druck LIQUIDTC255-0-1-K features an ambient to 255°C, Combination liquid bath (LI) and infrared (IR) functions

The GE Druck LIQUIDTC-255-01K Liquid Bath multi-purpose Temperature calibrators combine the portability of dry block calibrators with the flexibility of liquid immersion baths to enable the testing and calibration of virtually any shape and size of devices. The GE Druck LIQUIDTC25501K calibrators can be re-configured by the user to function as a liquid bath, as an infra-red black body source and as a dry block calibrator with interchangeable inserts. The latest heating and electronic control technology, combined with continuous liquid agitation of the fluid bath, provide high accuracy and stability throughout the large homogeneous measuring zone.

High capacity portable liquid bath
Standard factory configuration of the Liquid-TC-255 provides a 60 mm x 170 mm liquid bath with automatic liquid agitation.

Interchangeable liquid bath insert
Allows the calibration media to be simply and quickly changed to suit different temperature ranges, while retaining the automatic liquid agitation.

Infra-red black body source
A specially constructed insertion sleeve provides an emissivity of 1 (black body).

Dry well insertion sleeves
The GE Druck LIQUIDTC-255-01K Liquid Bath calibrator greatly simplifies the test and calibration of process sensor heads, probes, switches and thermometers, but optimum performance relies on a good fit of the device in the well insert. To facilitate this, a range of insertion sleeves are available with hole diameters to suit the most common probes and devices.

Liquid bath general features
Controller OFF Disables automatic temperature control at the last set point temperature to allow the calibrator settings to be changed part way through a test.
Manual control Allows the power output of the calibrator to be adjusted to control the rate at which the calibrator reaches the set-point temperature.
Set-point memory Allows up to four set-point temperatures to be stored in memory. The test sequence can then be activated with a single key press.
Test profile This function defines a temperature profile with a heating rate to the first set-point value, a test duration or soak time at set-point one followed by a cooling rate to a second set-point.
PC communications An optional USB cable is available for connection to a PC

The GE Druck LIQUIDTC25501K calibrator is factory configured as liquid baths and are provided with a bath cover to hold up to 5 devices while reducing heat loss from the surface of the liquid medium. For transportation a leak-proof sealing cover is also provided as standard. Optionally the temperature calibrators can be configured with additional capabilities including interchangeable liquid baths, a black body source and dry block interchangeable inserts.
