pH Meters Hanna Instruments' pH meters: Bench, Portable and ISE meters
pH Meters: Bench Models HI 110, HI 111, HI 112, HI 113 pH meters
The pH meter pictured is model number HI 111 which is one of a number of bench meters manufactured by Hanna Instruments. Other models both more basic and more sophisticated are shown on other pages (see navigation tabs on left). MBH Engineering can guide you based upon your requirements for lab equipment. Detailed specification sheets can be emailed to you showing the exact model needed. The model HI 111 features GLP (Good Laboratory Practice) data collection showing: offset, slope, date, time of last calibration. In addition to calibration at the standard 4, 6.86, 7, 9.18 and 10 buffer values, the user can also calibrate at two more custom defined points. The unit features ATC, opto-isolated RS-232 output and a mV scale for more measurements. Accessories not included with this instruments are an electrode holder stand (pictured), PC software and a serial cable as well as buffer, storage and cleaning solutions. HI 113 has all the same features but with two or three digit measurement of pH as opposed to the model HI 111 which is limited to pH measurement at 0.01 accuracy. The models HI 110 and HI 112 are missing the mV scale which can be very helpful in electrode diagnostics. These instruments can take advantage of Hanna's technical buffers which are available at pH values from 1.00, 2.00, 3.00 etc. to 13.00. When you need accuracy, Hanna's pH meters and electrodes perform. Most people are surprised when they find out the Hanna is the largest manufacturer of pH instruments and electrodes in the world. They continue to innovate in the field of pH measurement and lab equipment. We are proud to be a representative and stocking distributor for Hanna Instruments for the past fifteen years. HI 250, HI 251, HI 253, HI 254 Step up to the 250 series pH meters. This quartet of meters all sport an RS-232 serial port for computer connectivity, automatic memorized buffers and pH range up to 16.00/16.000. Other standard features include: an electrode stand, refillable glass electrode, temperature sensor and 12Vdc adaptor. Differences between the models are shown on the table below but can be summarized: HI 250 pH only, HI 251 pH/mV and the higher resolution models: HI 254 pH/mV, HI 253 pH/mV and ISE (ion selective electrode measurement). The meters look like the 110 series shown above.
