• More economical than silicone gauges
• Greater temperature range than silicone-filled gauges
• Anti-parallax dial for accurate readings
• Eliminate the risk of a leaking case and cross-contamination
• Hermetically sealed per ASME B40.3 standard to prevent fogging and protect against tough environments
• Rugged 304 stainless steel construction with a clear glass lens
• Recalibrate using the external reset screw

90131-02 Solar-Powered Adjustable-Angle Celsius Thermometer; 2.5" L by Digi-Sense

View readings from almost any angle by simply adjusting the angle of the head. Three-inch diameter adjustable head has an easy-to-read LCD. Requiring no batteries these thermometers are ideal in pilot plant or research and development applications where exact readings are required. The safety circuit prevents false readings. Each thermometer is housed in a weather-resistant 304 stainless steel (SS) case. Stem is 304 SS. An acrylic lens protects the face. To further protect thermometer order a thermowell from page 1052. Simply match the stem length to the probe depth "A" for the thermowell.
