Selection Guide

Models 309, 310, 311 F or C

PTC's 310 Series of surface thermometers are unilateral thermal sensors, which measure the temperature of a contact surface. These instruments are fully enclosed within a convex glass and a silicone rubber gasket seals the metal and glass parts against moisture.

The 310 series can be utilized in the lab as well as in construction measuring pavement and concrete temperatures prior to coating.

PTC Metrology is accredited by A2LA to ISO/IEC 17025 ANSI/NCSL and Z540-1 The calibration lab offers NIST traceable certification services. Our surface thermometers can be certified from 20°C to 190°C with an uncertainty of 500mK and from 191°C to 400°C with an uncertainty of 1000mK.

Mounting Options

These thermometers are easily and quickly installed. Horizontal areas are never a problem since the instrument is simply placed on the surface. For non horizontal areas, there are two methods of attachment:

The bottom area of the unit can be coated with a thin layer of silicone grease (available as an accessory) and the unit then pressed into position. The grease provides positive thermal contact and will hold the thermometer in place over all specified temperature ranges. On ferrous surfaces, a magnet and leaf spring (also an accessory) holds the instrument firmly against the surface. Simply bend the leaf spring and place the end over the top of brass nuts. ( Do not remove or turn brass nuts) See diagram to the right.

These instruments can be used wherever a surface thermometer is needed, but they are especially useful in applications where dirt or other contaminants may be a problem
