Designed to determine the penetration time of oil and other liquids through paper and other flat materials.
The instrument chamber has an orifice for holding the liquid medium and a clamping device for holding the material.
The penetration timer stops automatically after releasing the sample holder.
Double processed castor oil having viscosity of 700 ± 30 centipoises at 25º C or mineral oils of the same viscosity and comparable wetting characteristics are used.
Technical data
Provided with cooling system, Electronic PID control for constant temperature regulation with Electronic self starting timer as an optional accessory.
Temperature Range: ambient to 100º C, Electronic PID digital temp. controller control the temp. of the liquid 35 ± 1 degree C.
Penetration Timer: 999 second with 0.1 second
