Tecal H Range Dri-Block Calibrator
This range of temperature calibrators is ideal for advanced temperature calibration work where
programmability, switch testing and ramp/dwell functionality from the unit’s display and user
interface are required.
Each Tecal H model is shipped with one insert, soft-sided carrying case, calibration
certi cate and TechneWorks software with cable.
H Version: Set required Temperature and Calibrate; also programmable for switch test and ramp rate.
The H models have:
• 4 line by 20 character LCD and 8 button keypad for entering programs and viewing data.
• The ability to create, use and store programs and test results internally.
• Programming of set temperature, ramp rate, hold time, “pause on switch changeover”
operation and hold until pause pressed.
• A switch test input for monitoring hydraulic thermostats.
Tecal 140H
Using advanced peltier technology and state-of-the-art mechanical and electrical components, the
Tecal 140H can rapidly cover the complete temperature range where speed is of the essence without
loss of accuracy or stability. The heater block, with a de ned measuring zone of 5 cm from the
bottom of the block, allows for di erent length/active area sensors. Although the quoted accuracy
and stability is ±0 .3°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.
