The Checkline RX-1600 Durometer is the standard model for good reason. The gauge features a full-sized dial face for readability to within 1/2 point. The RX-1600 offers the maximum accuracy available in a dial model gauge at a minimum cost.
Type M Durometers require test stand RX-OS-3 per ASTM D2240.
Available Scales: A, B, CF, D, DO, M, O, OO, OOO, OOO-S, RR (Asker, ISO, DIN & JIS Scales also available, inquire)
All RX-1600 models are supplied with a NIST traceable calibration certificate.
