813 7. Heating and cooling technology Heating/Water baths GENERAL CATALOGUE EDITION 20 E & OE. Water baths WNB/WNE 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 Water baths WNB 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. 1 Memmert Specifications Working-temperature range: at least 5 °C above ambient temperature up to +95 °C with additional boiling mode (+100 °C) Setting temperature-range: +10 °C up to +95 °C and boiling mode Power supply: 230V, 50/60Hz; 115 V, 50/60 Hz no extra cost Type Capacity Housing (W x D x H) Internal dimensions (W x D x H) Power consumption Weight PK Cat.
