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: Fuzzy-supported; PID microprocessor controller with integral autodiagnostic system and fault indication. Solid state switching unit. 2 class A; 4-wire Pt100 sensors; mutually monitoring and controlling the performance at the same temperature value. Digital timer from 1 min to 999 hours for: On (continuous operation). Delayed On. Hold; or set temperature-dependent Hold; with fixed dwell time. Digital display (LED) of all set parameters; such as temperature; time and alarm values. Calibration facility on controller. With audible and visual alarms at programme end; as input keypress confirmation and if low liquid level occurs (heating is switched off automatically). Triple Overtemperature Protection: In case of overtemperature due to a fault; the heating is switched off at approx. 10 °C above the set temperature (fixed value). Independent; protection class 3.1; TWW electronic overtemperature controller; or protection class 2; TWB overtemperature limiter; are adjustable in set-up menu by the user. Class 1; TB mechanical temperature limiter switches the heating off at approx. 30 °C above max. bath temperature. Set value display resolution: 0.1 °C below 99.9 °C; 1 °C above 100 °C. Textured; grade 1.4301 (ASTM 304); corrosion resistant stainless steel housing. Without lids - please order separately.
