SUBJECT: Wahl DIGI-STEM Self Powered Digital Read Thermometers Series DST 200 and DST 300

The Wahl DIGI-STEM digital read self powered thermometers series DST 200 and DST 300 have been reviewed and found to comply with the applicable provisions of the Grade A Pasteurized Milk Ordinance (PMO) for use in milk storage tanks and refrigerated rooms. These battery operated thermocouple based thermometers may be used in storage tank and room applications where mercury-in-glass or bi-metal thermometers have traditionally been used.

These thermometers have been found to meet the applicable Appendix H criteria. They may be adjusted if necessary. A low battery results in a flashing but accurate read. Loss of battery will result in a blank read.

Both series have thermowell or 3A sanitary fittings and connections.

Copies of this memoranda are provided for distribution to state milk control agencies and state milk sanitation rating officers in your region. States desiring further information or copies of materials concerning this equipment contact:
