Grease And Bitumen Testing Instruments

Product Details:

TEST METHOD
Test Method
The sample is cast in shouldered rings and heated at a controlled rate under the weight of a steel ball. The softening point is the temperature at which the bitumen disks soften and sag downward a specified distance.

 

Conforms to the specifications of: ASTM D36, E28; AASHTO T53; IP 58, 198; NF T 66-008

 

FEATURES:- 1) Temp. Rise : Setable From Range 0.1deg C To 9.9 Deg C.
2) Method Of Detecting Softening Point : Manual.
3) Microprocessor Based Temperature Control Unit With All Necessary Interlock.
4) You Can Set 10 Deg Prior To Expected Softening Point. Once It Will Reach There It Will Give You Audio Visual Alarm And Will Maintain That Temperature Until You Press A Reset Button.( Upto This Time You Don’t Have To Attend The Equipment.)
5) After Reaching Preset Temperature, You Have To Set Ramp Rate Of Temperature Rise Range From 0.1 Deg C To 9.9 Deg C Per Minute. After Setting The Ramp Rate, You Have To Press The Start Button.
6) Now, When You Detect Softening Point, Press Hold Button The Temperature Display Will Hold Until You Press Reset Button. The Hold Display Of Temperature Indicate Your Softening Point.

Benefits:-
· It Will Follow Exact Astm Procedure Without Much More Manual Intervention.
· Operator Will Remain Free Until It Reaches Preset Temperature.
· The Facility Of Ramp Rate Allow The Operator To Carry The Test At The Speed It Desire.
· All Necessary Interlock Will Detect The Problen Automatically.
· User Friendly.
· The Hold Display Of Softening Point Facility Will Allow The Operator To Note Down The Reading With Some Time.
· Printer Facility (optional With Extra Price). Will Reduce The Error Of Manual Mistake.

Test Method
The ASTM D2265 dropping point test permits higher temperatures than the ASTM D566 method and
uses a different heating procedure: the test cell is inserted in an aluminum block oven maintained at
a constant temperature that is higher than the expected dropping point of the sample. The sample
temperature then rises to the dropping point without operator control.

Features and Benefits

• Conforms to ASTM D2265 and D4950 specifications
• Four-sample testing capability
• Microprocessor programmable high accuracy temperature control

APPARATUS :- Tests dropping points of lubricating greases at temperatures of up to 400°C
(752°F). Includes thermostatically controlled aluminum block oven and six complete dropping point
assemblies. Six-place oven has large viewing ports with fluorescent backlighting for excellent visibility.
Microprocessor PID control provides quick temperature stabilization without overshoot and the bath
is protected by an overtemperature control circuit that interrupts power should block temperature
exceed a programmed cut-off point. Dual LED displays provide actual and setpoint temperature
values in °C/°F format. Communications software (RS232, etc.), ramp-to-set and other enhanced
features are available as extra cost options. Microprocessor temperature control with digital readout
and overtemperature safety cut-off maintains block temperature with ±0.5°C stability.

Included Accessories:-

Dropping Point assemblies consisting of indented test tube and grease cup.
