ph meter
HI 98185 is a waterproof, portable meter designed for demanding applications. This meter measures pH/ ORP/ ISE and temperature. Choose from 7 standard pH buffers and 5 custom pH buffers to obtain up to five point calibration and achieve high precision readings with a pH accuracy of ± 0.002 and up to ± 0.001 pH resolution. HANNA' s Calibration Check™ maintains a history of past calibrations and monitors the pH electrode and buffers during subsequent calibrations for any signs of wide calibration variances due to a dirty or broken electrode or contaminated pH buffers. In measurement mode, the electrode' s percent condition is continuously displayed. Exchange the pH probe for an ORP probe to obtain mV readings in the ± 2000 mV range. HI 98185 adds direct ion concentration readings for ISE' s and the results are displayed in ppm. The ion charge or nominal slope can be entered manually. HI 98185 supports 15 different ISE sensors by default and can be calibrated with up to five points and 6 standard buffers ( choice of units) . This unit allows an extensive choice of measurement units ( ppm, ppt, g/ L, ppb, ug/ L, mg/ mL, M, mol/ L, mmol/ L, % w/ v, user) and has an expanded measuring range of 1.00 x 10-7 to 9.99 x 10-10. Press Auto-Hold while measuring and once stabilized, the current reading will remain displayed for your convenience in documenting. Switching to log-on-demand mode allows users to record and save up to 300 samples. This data can later be transferred to a PC with the USB connection and HANNA' s HI 92000 software. “ Out Of Calibration Range Warning” can be engaged to keep the user informed of the current calibration and helps to avoid taking measurements that are out of range. A backlit, graphic LCD provides easy to read resolution even in low-lit conditions. A combination of dedicated and soft keys allows easy, intuitive operation in a choice of languages. Comprehensive GLP data are directly accessible by pressing the GLP key. Access the contextual Help Menu to obtain on-screen information and assistance about each feature at the touch of a button. Designed for field use, these instruments can be operated with one hand and are supplied in a rugged carrying case. With an extended battery life of up to 200 hours users are assured long operation. The inductive charger can either be plugged into a standard 115V socket with the included adapter or a 12 VDC source, such as a car' s 12 V accessory outlet. This meter come equipped with the HI 72911B pH/ temperature electrode with rugged, titanium casing.
