TU Tenderometer: Product Description 

The TU Tenderometer for testing pea maturity is the world's most widely used tenderometer.  These systems have proven to be the most dependable, accurate and trouble-free instruments ever created for grading pea quality.  Accurate readings can save thousands of pounds per day for a medium to large operation and quickly pay back the initial investment.  The Tenderometer can be used in the field when powered by a mains voltage generator, which can also be supplied by Spectronic CamSpec Ltd.

In numerous industry and government trials, it has been proven time and again to be the most accurate, reliable and easy-to-use instrument of its kind.  The TU system comes calibrated and reads in traditional Tenderometer Units.  Moisture sealed, for use in a processing plant, the TU requires no maintenance and yearly re-calibration of the system is easily performed by Spectronic CamSpec Ltd with fresh peas each season.


"The digital TU Tenderometers will have paid for themselves by holding more product in the Garden bracket, rather than dropping into Catering, due to unit accuracy."

Colven Wilson, Technical Manager at Eyemouth Freezers Ltd

Tenderometer Features

Simply load the sample and press start.  The system automatically clears the last reading, completes a test cycle and displays the results in industry standard Tenderometer Units.

For 40 years, pea processors worldwide have relied on these tenderometers to determine harvest dates, buy on grade and position harvesters for the most effective crop yield.  With profits at stake, a point or two off the standard can be very costly.

Standard Units

Designed to indicate tenderness in tenderometer units, the measurements given by the tenderometer correlate directly to pea maturity grades.

Easy to Use

Simply load the peas, shut the door, press start, record the reading, unload and repeat - that's it.

Incredible Accuracy

Compared to other conventional tenderometer systems, the readings are taken in a much tighter range, making the average significantly more precise.


Supplied with: FTA-TU Load cell, CS-1-TU Test Cell, Certificate of Calibration and Operating Manual.  The TU system comes calibrated with fresh peas for tenderometer use.  Return to Spectronic CamSpec Ltd annually to maintain calibrated TR value measurements.
