Waterproof ATC pH/Ion Meter - LCD Display

• ISO9022 Certified 
• Measure pH, specific ion (ISE), ORP, and temperature 
• Automatic temperature compensation 
• Dual level display with graphic symbols - pH/mV or temperature 
• 5 Memorized pH buffer values 
• READY function allows calibration only after electrode stabilization

This waterproof microprocessor-based pH meter is housed in a rugged ABS casing built to last. The meter is easy to calibrate and use; an auto-instruction feature guides the user step-by-step through the calibration process with graphic symbols and 5 memorized standard buffer values. Because the electrode requires time to stabilize between buffers, the display reads "READY" when electrode has stabilized. Unlike many pH meters that only allow calibration at 7 pH, this meter allows calibration at any of the 5 memorized buffers (4.01, 6.86, 7.01, 9.18 and 10.01). The second point of calibration may be any of the remaining buffers. The HI 9025 will also calibrate with one buffer if 1 point calibration is desired. Optional ORP (mV) probes available below. Price includes meter, double-junction plastic-bodied gel filled pH electrode, buffers 4 & 7, temperature probe, rugged carrying case and instruction manual.

Three optional ORP electrodes are available: all have a single ceramic junction µ1.2mm with flow rate of 15-20 µL/H, coaxial cable, BNC connector. The HI 3230B combination platinum probe and the HI4430B combination gold probe have a range of 0-80° C, gel cell in an Ultem^R body, with a pressure rating of 1.5/21.75 bar/PSI; these are designed for general use. The HI3131B is a refillable glass-bodied platinum single junction (ceramic µ1.2mm) with 15-20 µL/H flow rate, coaxial cable, temperature range of -5 to 100° C and pressure range of 0.5 to 7.25 bar/PSI. The HI3131B is designed for titration applications.
