pH/ ORP Benchtop Meter with Three Point Calibration HI 2213

The HI 2213 is a pH and temperature benchtop meter. HI 2213 can also measure oxidation reduction potential ( ORP) in the mV range. A relative mV feature is provided. Calibration can be performed at up to three-points using five standard and two custom buffers. This instrument features manual or automatic temperature compensation with the HI 7662 temperature probe. GLP ( Good Laboratory Practice) feature provides data consistency. A calibration reminder can be set to alert the user, that too much time has elapsed since the last pH calibration and a new one should be performed. Specification: Range pH – 2.00 to 16.00 pH mV ± 699.9 mV; ± 2000 mV Temperature – 20.0 to 120.0 º C Resolution pH 0.01 pH mV 0.1 mV; 1 mV Temperature 0.1 º C Accuracy @ 20° C pH ± 0.01 pH mV ± 0.2 mV; ± 1 mV Temperature ± 0.2º C ( excluding probe error) Relative mV Offset Range ± 2000 mV pH Calibration automatic, up to three points with five standard buffers available ( 4.01, 6.86, 7.01, 9.18, 10.01) , and two custom buffers Temperature Compensation manual or automatic from – 20.0 to 120.0 º C ( -4.0 to 248.0º F) pH Probe HI 1131B glass body pH electrode with BNC connector and 1 m ( 3.3’ ) cable ( included) Temperature Probe HI 7662 stainless steel temperature probe with 1 m ( 3.3’ ) cable ( included) Input Impedance 1012 ohm Power Supply 12 VDC adapter ( included) Environment 0 to 50° C ( 32 to 122° F) ; RH max 95% Dimensions 235 x 222 x 109 mm ( 9.2 x 8.7 x 4.3” ) Weight 1.3 kg ( 2.9 lbs.)
