Description

The Wahl Digi-Stem® DST550 Digital Thermometer are designed for use wherever the recording of Minimum and Maximum temperature is required.  Min-Max data is recalled by depressing an operator interface switch.

Our Digi-Stems® are known for their reliability and rugged cases.  The housing is stainless steel with a NEMA-4X rating.  Dimensions are 5.3 inches wide x 4.3 inches high x 2.7 inches deep (13.5cm wide x 10.9 high x 6.9 cm deep).  The large 1 inch high LCD display is readable from 30 feet away.

Choose from rigid, remote, or adjustable angle RTD  probes built to order to customer specification and sold separately.  The DST550 Series features programmable “RØ” for “matching” the sensor to meter.

The DST550 is powered by and shipped with one C size, Lithium Thionyl Chloride, 3.6V battery.  Due to shipping restrictions, meters with this battery must be shipped by ground transport.  For international or air shipping, choose the "NB" option for the meter only with no battery included:  purchase the required battery from a supplier near your location.
