The latest generation of water baths, a combination of high-grade, anti-corrosion
Memmert
stainless steel and state-of-the-art technology. Two performance classes available:
"Basic" and "Excellent", tuned to varying requirements and applications.
Basic: the water bath for routine processes, with integral timer adjustable from 1 min. up to 99.59 hrs, and with
delayed switch-on and programmable hold time.
Excellent: with enhanced features for overtemperature protection, liquid level monitoring and continuous, long-term
tests using two high-grade Pt100 sensors. The integral timer range is from 1 min. up to 999 hrs and allows a
setpoint-dependent hold time to be programmed, in addition to all the Basic-level features. Audible alarms for
overtemperature, low liquid level and programme end make operation even more convernient.
The new generation oil bath range differs from the Excellent water baths by their temperature range of up to +200°C
and by incorporating an adjustable, class 2 temperature limiter as standard.
Interior - Heating Concept:
- easy-to-clean, grade 1.4301 (ASTM 304), laser-welded, stainless steel interior, reinforced by deep drawn ribbing
- corrosion-proof, large-area heating surface on 3 sides of the tank
