TM Make hardness testers, models, RHT,RBHT are manually operated. These modelsare designed and developed after years ofexperience in this field. All the models aremanufactured understrict control at all manufacturing stages.These are suitable for testing hardness ofmetals and alloys of all kinds, hard or soft,whether flat or round etc. or of irregularshape. These Testers aresimple in design and easy to operate, still yetquite sensitive and accurate. Various modelsfrom the wide range are available forInstitutes, Quality Control Laboratories, Tool-Rooms, Heat Treatment Dept., R & DLaboratories, etc. These models strictlyconforms to IS:1586-Part-I, II:2012, BS:891-Part 1 & 2 for Rockwell Hardness testing.

TRH-LM Digital Rockwell hardness tester is based on the principle of ROCKWELL. It is used to measure thehardness of carbon steel, alloy steel, cast iron, non-ferrous metal and engineering plastics. It has thecharacteristics of high accuracy, wide measuring range, automatic loading and unloading of main testforce, digital display of measurement results, data printing and external computer communication.Digital Rockwell hardness tester has novel appearance, intuitive digital display and computer control. It hasstable performance. It is a high-tech product which integrates mechanical and electrical technology. It canbe used for hardness testing of Rockwell scale.

it is widely used to measure the Rockwell hardness offerrous and non-ferrous metals such as quenched steel,tempered and annealed steel, hard alloy steel, aluminiumalloy, copper etc. in the labs of research institutions,colleges, factories and mines.

Hardness Tester TLRH-CURVE, adopted the international advanced closed-loop sensor controltechnology, to achieve full automatic control and hardness testing process. The load system uses highprecisionforce value sensor and central controller to form a closed-loop loop to achieve full microsecond level tracking and control of the booster process.

The measurement system uses high-precision displacement sensor with a hardness value resolution of 0.1 HR for accurate hardness results.

RHTNE-T machines for Rockwell & Rockwell Superficial tests a preliminary test force in first applied and then digital indicator isautomatically set quickly thereafter an additional test force isapplied without removing the preliminary test force. When thepenetration is stabilised, the addtional test force is removed andthe hardness number is shown directly on the indicator.

• Sutable For Rockwell & Rockwell Superficial Tests.
• Manually Operated.
• Auto Zero Setting Dial Gauge.

Multifunction digital twin Rockwell hardness tester has high level automation, stable and reliableperformance, it can meet the Rockwell hardness test requirements of all metal materials. it is equippedwith sophisticated sensors so that can test data more accurate ; 5.6 inch digital LCD screen providecomprehensive data for quality control. It is easy to preserve the data for a long time.
Main function and features

1. The machine can meet the metal Rockwell and superficial Rockwell hardness test requirements;hightest precision ;good repeatability;
2. Equip with sophisticated sensors, more accurate test results, leading load structure design, can easilyswitch test force;
3. It is automatic to test when the workbench lift up to certain height, then indicate the hardness valueand test data directly;
4. With Chinese and English operation interface, can be set in test method quickly, the upgraded controlsystem is more stable;
5. Indicate the hardness value, hardness unit, conversion hardness, test force, indenter type, minimumthickness, dwell time, test number, test process on the LCD screen directly; Built-in printer can printthe measure count, hardness value, average value, maximum and minimum values, rangedatafor ourcustomer;
6. One-time casted molding shell, stable structure and it is not easy to be out of shape.It can work underharsh environment; the shell coating adopted car paint technology with white color. it has strong scratchresistance capability and still look bright as new after use many years;

FEATURES 
1. Decent design, high testing precision and simple operation.
2. Adopted car painting technology. The paint shade do not fade and machine looks like new over year.
3. The Elevating screw is guided in a hardened & ground bush, not allowing movement of elevating screw more than 0.05mm when raised to full heigh
4. An antifriction linear movement with almost no clearance is provided for a perfect movement of diamond holder. this enable testing of small dia. pin or ball upto 3mm dia.
5. The machine provided with manual zero setting dial indicator having least count of 0.5 HR and automatic load selection by knob.
6. The machine can be upgraded to digital by replacing with digital dial indicator (optional)
