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 convenient. 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.
