User manual for the PCE-PTR 200 Penetrometer
Contents
1. 1 Introduction The Penetrometer PCE PTR 200 penetrometer is very useful for testing the maturity of fruits This digital penetrometer offers higher accuracy and resolution than any other analogue device With 20 kg it has a high capacity The indication units can be selected from kg Ib and N Thus it also offers the option of measuring compressive and tractive forces The penetrometer supports saving not only the current measurements but also the maximum value In all modes the penetrometer can be set back to 0 whilst the tare function can be performed over the whole measurement range The penetrometer PCE PTR supports many features amongst which is a key for quick and slow response times whilst the display can be selected for forward or backwards indication The device can be also installed at a stand for a fixed measurement point The battery consumption is very low while it can also function on an adapter The battery state is indicated by the device so the operator is always informed about the power consumption of the device The penetrometer features a microprocessor switch and an overload protection Additionally the device can be purchased with an optional test stand 2 Safety Precautions Please read the following instruction manual before operating with the device Damages caused by disregard of the instructions written in this manual are excluded from any warranty or liability his device is only designed for the applications me2. 38 15 95 8600 8 58 16 15 8800 8 77 16 35 9000 8 97 16 55 9200 9 17 16 75 9400 9 37 16 95 9600 9 57 17 15 9800 9 77 17 35 10000 9 97 17 55 10200 10 17 17 75 10400 10 37 17 95 10600 10 57 18 15 10800 10 77 18 35 11000 10 97 18 55 11200 11 17 18 75 11400 11 37 18 95 11600 11800 11 77 19 34 12000 11 97 19 54 12200 12 17 12400 12 36 12600 12 56 12800 12 76 13000 12 96 13600 17 Manual 3 www industrial needs com Applied Pressure with Penetration Tip O 11 3 mm Range 0 20 kg Indication on Penetrometer g EB T ERE B BG E m that te da T Bia BAB i0 17 42 47 ij 1B 18 15 1 amp 8 15 Applied Pressure kg cm 2 11 Disposal Batteries may not be put in the household waste They have to be given in the set up collection points NOTE This instrument doesn t have ATEX protection so it should not be used in potentially explosive atmospheres powder flammable gases Please contact PCE Instruments if you have any questions concerning our products service etc Here you will find an overview of our measuring devices X http www industrial needs com measuring instruments htm Here you will find an overview of our scales and balances http www industrial needs com balances htm Here you will find an overview of our laboratory equipment http www industrial needs com laboratory eguipment htm Here you will find an overview of our control systems http www industrial needs com control systems htm W
