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.
