2. ACCESSORIES

2.1. THERMOCOUPLE

Thermocouple Wire Type“K” :

Thermocouple will be attached directly onto metal surface of the work-piece using a Thermocouple Attachment Unit. This consumable type of thermocouple gives the greatest accuracy.

Material Glass Fiber individual wrapped, 2 cores for Chromel-alumel
Range0°C ~900°C
Packing100ML/roll (328’/roll)

Thermocouple Putty

This is used to insulate the hot junction of thermocouples, so as to avoid temperature misreading caused by the effect of radiation.

Material Ground Alumina, Silica Sand, Ground Silica Sand, China Clay, Ball Clay, Ground Bauxite, Alkaline, Sodium Silicate.
Packing0.5kg/jar

Thermocouple Attachment Unit

This is used to attach thermocouple wire directly to the work-piece. The penetration will only 0.2~0.3 mm, causing no damage to the work-piece.
