Infrared Digital Thermometers Kessler carries the complete line of Sentry Infrared (IR) Digital Thermometers. They feature a non-contact method of measuring temperature, quick measurement response and a wide variety of applications. Temperature is measured by pointing the unit at the object to be measured until the object′s temperature is displayed on the unit′s LCD screen.
ASTM Thermometers Kessler′s rigid manufacturing tolerance and inspection ensure the production of ASTM thermometers that are well within the dimensional and accuracy specifications of E-1 and E-77 of the American Society for Testing and Materials (ASTM). To order a copy of the test method E-77, please use Catalog No. ASTM E-77.
Hand-Held Refractometers Chasebrand refractometers are precision optical instruments used to measure the concentration of aqueous solutions. They are simple to use and require only a few drops of solution. They are used throughout the food, agricultural and manufacturing industries.
All Chasebrand refractometers are available with a Full Laboratory Report with traceability to instruments certified by N.I.S.T. Each of these refractometers has a unique serial number engraved into the metal housing.
To order with N.I.S.T. traceability, add the suffix ′′NIST′′ after the catalog number.
Low Toxic Non-Mercury Thermometers Kessler′s new Low-Toxic Non-Mercury thermometers are suitable for all applications where a safe and accurate alternative to mercury is required.
Kessler′s rigid manufacturing tolerance and inspection ensure the production of ASTM thermometers that are well within the dimensional and accuracy specifications of E-1 and E-77 of the American Society for Testing and Materials (ASTM). To order a copy of the test method E-77, please use Catalog No. ASTM E-77.
Environmental Chamber Bottle & Specialty Thermometers A precision mercury-in-glass thermometer, graduated in 0.5 degree division. Teflon encapsulated for extra safety mounted in a clear polycarbonate bottle with mineral oil (sterilized sand for Oven model 1732), for use as a heat sink prevents rapid change of indication when chamber is opened for inspection.
Jointed Thermometers Kessler ST (Standard Taper) jointed thermometers are uniquely fabricated by enlarging and molding the stem glass to the required size, then precision grinding to a true standard taper for a perfect fit. This style of fabrication avoids the inherent weaknesses found in ordinary jointed thermometers built from 3 separate pieces of glass.
