The standard diameter is .250″ on all models. 5/16″ and 3/8″ diameter stems are available and recommended for extra strength on hand-held applications for stem lengths 36″ and over.

Heads & Bezels

All Models, polished Type 302 Stainless Steel.


All Models are guaranteed accurate to be within plus or miun 1% of the full scale. The temperature readings are stabilized within 40 seconds.

Pointed Stems

Optional and available on all models. Excellent for probing asphalt, compost, soil, froxen foods or other semi-solid materials, for a quick reading.


Thermowells should be used whenever the stem would be exposed to pressure, corrosion or shear forces. Thermowells also make it possible to remove the thermometer without inter fering with processes, pressure or any contents.

External Reset

All models are available with or without an external reset, except on models 910B, 910C and 910E, which can be available, with reset, upon request.


For correct temperature measurements, stems on all models in all ranges need to be immersed 2 inches in liquid, and 4 inches in gas except for ranges 0/100°F, 25/125°F and 0/50°C which require 3.5 inches in liquid and 5 inches in gases.
