High-grade, corrosion-resistant stainless steel in combination with innovative control engineering. Available in two performance classes: Basic and Excellent, tailored to different requiremetns and applications.

Basic: The bath for standard temperature control tasks.
Excellent: The bath for higher demands in terms of overtemperature protection, level monitoring, reliable results over long-term applications thanks to two high-end Pt100 sensors.

Standard scope of delivery, without cover

Control systems:

• Micro-processor PID-temperature control with integrated self-diagnostics system to find errors quickly
• non-contacting switching element
• one Pt100 DIN-class A in 4-conductors measurement
• integrated digital clock from 1 min. to 99.59 hrs. for:
  ON permanent operation
  WAIT (delays on for duration and limited-time operation)
  HOLD
• digital display (LED) of target and actual temperature (resolution 0.1°C), as well as (remaining) programme run time
• Status-LEDs to monitor programme run

Overheat protection (double):

• in case of error-caused excess temperature, the heating is turned off at ca. 10°C above target temperature
• mechanic temperature limit TB protection class 1 to turn off heating at 30°C above max. bath temperature

Structure stainless-steel housing:

• Substance 1.4301 (ASTM 304), corrosion-resistant

Interior - heating concept:

• easy-to-handle, stainless steel workspace enforced by deep-drawing ribbing, substance no. 1.4301 (ASTM 304), laser-welded
• corrosion-protected, large-sized heating placed on 3 sides

Temperature range:

• from +30°C (but at least 5°C above room temperature) to +95°C with additional boiling level (100°C)

Power:

• 230 V (+/- 10%), 50/60 Hz

Standard scope of delivery, without cover

Control systems:

• PID-micro processor control with fuzzy support and self-diagnostics system to find errors quickly
• non-contacting switching element
• 2 Pt100-sensors DIN-class A in 4-conductor measurement with changing monitoring and function adaption at exactly the same temperature
• digital countdown clock from 1 min. to 999 hrs. for:
  ON (permanent operation)
  WAIT (delays on)
  HOLD or HOLD dependent on target temperature, with "Holding time guarantee"
• digital display of all default values: temperature, alert (resolution 0.1°C) as well as time
• calibration possibilities at the control
• acoustic and optical display in case of alarm, programme end and to confirm receipt as well as at low filling level; heating is turned off automatically

Overheating protection (3-fold):

• in case of erroneous excess temperature, the heating is turned off at 10°C above target temperature
• separate electronic temperature selection guard TWW protection class 2, can be adjusted by customer in set-up
• Display resolution/setting accuracy 0.1°C to 99.9°C; 1°C from 100°C
• mechanic temperature limit TB protection class 1 to turn off heating at ca. 30°C above max. bath temperature

Like WNE waterbaths, but with temperature selection limiter, temperature range max. 200°C, digital definition of setpoint and indication of actual value, precise to one degree C.

for precise working with temperatures of +10°C or higher. The temperature is regulated by the electronic waterbath controller with a precision of ± 0.1 K.Snap-on technology for easy attachment to the bath. Suitable for waterbaths of all sizes.

Incl. support frame (for test-tube racks or perforated shelves with support basket) for fitting into water baths, with electronic speed control (speed min. from 35 to 160 strokes per minute; horizontal back/forth movements).

With perforated mounting shelf (stainless steel) with grid perforations to take clips for conical flasks for models WNB/E 14 and WNB/E 22
