Tecal S and H range Dri-Block Calibrator
This range of temperature calibrators is ideal for calibrating temperature sensors used in the
food and pharmaceutical industries in addition to calibrating any sensors used in the temperature
range outlined in the specifications below.
S Version: Set required Temperature and Calibrate
H Version: Set required Temperature and Calibrate; also programmable for switch test and ramp
rate etc.
Tecal 140S/H
The Tecal 140S provides a complete system for calibrating most types of thermal sensors used
in the temperature range of -40°C to 140°C which includes “K” type thermocouples commonly
used in the food industries, cold storage rooms and environmental monitoring systems.
Where automation in both the field and laboratory are required, the combination of the Tecal
140H with the UPI (see page 13) saves time and money. The user can set the program and leave
the unit to calibrate the probes, automatically storing the results in memory. This allows the user
to attend to other tasks and when convenient download the results to a computer to print the
calibration certificate.
Using advanced peltier technology and state-of-the-art mechanical and electrical components,
these calibrators can rapidly cover the complete temperature range where speed is of the essence
without loss of accuracy or stability. The heater block with a defined measuring zone of 50mm
from the bottom of the block allows for different length/active area sensors. Although the quoted
accuracy and stability is ±0 .2°C & ±0.05°C respectively, one can often achieve an accuracy of
±0.1°C and a stability of ±0.02°C with high class RTDs and thermocouples.
