External controllers

for Kjeldahl block digestion systems

TZ: Temperature / time controller

This controller can be easily programmed for the automated operation of KJELDATHERM, CSB and SMA digestion units. Can be mounted on the side of the system in order to save bench space.

Features

• 9 programs with 9 steps ensure optimal control of the three essential digestion phases: heating up, digestion and cooling
• Programmable temperature range (room temperature up to 430° C)
• Accuracy < 0.5 % in the upper temperature range
• Suction is turned on automatically when the previously defined block temperature is passed
• Automatic control of fume suction and cooling water flow
• Optic and acoustic messages
