LiquiCal™ is a range of high performance liquid baths used for high precision temperature calibrations. The baths can be controlled via PC allowing for automated calibration and ramp control. It can be ran as a stand alone unit as well. LiquiCal™ provides high accuracy along with a large immersion depth, high stability, fast temperature changes and quiet runs.
The models cover temperatures from -80°C to +300°C, all having the same exterior dimensions, bath openings and liquid filling volume except for the micro baths (LiquiCal™ SM/HM) which are far smaller facilitating mobility.
Complete Automated Solution
The LiquiCal™ baths can be integrated with the Ellab Temperature Standard (ETS) and Valsuite™ Pro calibration and validation software for complete automated calibration and control. The software will control the ramp, stability time and automatically calibrate Ellab's data logging equipment.
A convenient overflow reservoir captures any excess fluid that results from fluid expansion. The bath's 15.9 L (4.2 gallon) tank can easily be emptied by drain when needed.
Liquids for LiquiCal™ Baths
To obtain optimal temperature stability and homogeneity in the calibration zone, liquids with the lowest possible viscosity (< 25 CST) are preferred. Ellab supplies a range of liquids in 3.8 L (1 gallon) containers covering the temperature range of -90°C to +300°C safely.
|Ellab Halocarbon Oil Low
||-90°C to +90°C
|Ellab Low Temperature Liquid
||-80°C to +5°C
|Ellab Standard Oil
||-30°C to +160°C
|Ellab High Temperature Oil

One Bath/One Oil Concept
Using Ellab standard oil within a temperature range of -30°C to +150°C together with the LiquiCal™ SL bath, you will be able to cover most validation applications, including:
Ellab Temperature Standard
- Sterilization using autoclaves and retorts
- Pasteurization using plate heat exchangers
- Testing using environmental chambers
- Chilling using refrigerators
- Storing in freezers
The traceable ETS
provides an extremely accurate temperature calibration. The ETS is available in 3 different versions and comes with calibration certificates traceable to NPL. The ValSuite™ Pro software, along with the ETS and the LiquiCal™ bath, provide an automatic setup which simplifies the calibration process and saves time.
ValSuite™ Pro Software
The ValSuite™ Pro
Software allows for a semi or full-automatic pre and post calibration of cable probes or wireless loggers. Using the intuitive menus all data necessary for software calibration is processed, and offset values are generated that are stored in the software. For the TrackSense® Pro wireless loggers and E-Val Flex intelligent cable probes, a firmware calibration routine is recommended on a regular basis, and a user alert can be programmed into the memory for smart handling.
Ellab calibration software uses a point-to-point method and can handle multiple points using only interpolation. When choosing the semi-automatic calibration only an ETS is connected. In a full-automatic calibration both the ETS and LiquiCal™ bath are in operation. The following performance criteria can be set:
- Maximum allowed calibration bath fluctuation band and time
- Holding time
- Maximum allowed temperature standard fluctuation
- Maximum sensor temperature deviation and pass time
All setup conditions and acceptance criteria together with actual values and deviations are shown in the calibration report.
