Water baths WNB
A combination of high-grade, anti-corrosion 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 1min. 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.

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
Control:
-microprocessor PID-temperature controller with integral autodiagnostic system and fault indicator
-solid state switching unit
-one, class A, 4-wire Pt100 sensor
-integral digital timer from 1 min. to 99.59 hours for:
Continuous operation
Wait (delayed On for continuous and limited timed operation)
Hold
-digital display (LED) of set and actual temperature and of (remaining) programme time
-LEDs for indication of programme status

Overtemperature protection (dual):
-if an overtemperature condition occurs due to a fault, heating is switched off at approx. 10°C above the set temperature (fixed value)
-an independent, mechanical, TB class 1 temperature limiter switches the heating off at approx. 30°C above max. bath temperature

Without covers - please order separately.
