Description

The PLB 150 portable liquid bath  have a large calibration volumes, 60mm x 170 mm deep, which make it ideal to use as portable liquid bath. Stirred liquid baths are suitable for temperature sensors of all types and shapes and can provide smaller calibration uncertainties ( stability, uniformity and accuracy) than dry blocks calibrators.

The PLB 150 Portable stirred liquid bath comes in two models:

PLB 150-TS Temperature calibrator/source with no inputs

PLB 150-TC Temperature Calibrator/source with inputs for reference sensor and sensor under test

Stirred liquid bath use
As a liquid bath the sensor is placed directly into the block with-out the need of special drilled inserts. When used as a stirred liquid bath, the PLB 150 achieve increased performances, similar to those of larger and expensive laboratory liquid bath. As the fluid is inserted directly into the block, the overall performance of the PLB 150 is superior to similar products which use liquid container.
The magnetic stirred ensure excellent homogeneity. The speed can be changed using the on board potentiometer to suit different fluid viscosity.

Multi-functional
The PLB 150 can be converted with different accessories to a Dry block, infrared and surface temperature calibrator. When used as Infrared calibrator, the large block diameter make it suitable to test hand held infrared thermometer with large distance to spot ratio.
When used in dry block mode, the large block allow for testing several sensors at the same time or large diameter sensors.
