HANNA Manuals

This manual introduces the features and characteristics of HI 98230 and HI 98240 portable printing and logging pH/temperature meters, including electrode types, electrode maintenance, automatic calibration, data recording, printing, and saving.

The SALINTEST HI 98203 Salinity Concentration Pocket-sized Meter measures sodium ion concentration, using a double junction reference for highly stable readings

The document introduces the use of the pNa HI 98202 soft water tester. The instrument uses a sodium ion-selective electrode to determine the activity of free sodium in solution (pNa = -log aNa). In dilute solutions, the activity coefficient is nearly 1 and in such solutions pNa is a good indicator of the sodium ion concentration. The relationship between the pNa scale and the g/L Na+ scale is explained in the chart below. A double junction reference is used to ensure a highly stable reading. If you suspect that the calibration has drifted, you can recalibrate the meter by using a solution of known concentration. Adjust the reading with the calibration trimmer.

This document is about the specifications, warranty, accessories, etc. of the HI 98201 pocket-sized ORP meter.

This manual provides instructions for using the HI 98186 Dissolved Oxygen Meter

HI 98170, HI 98171 and HI 98172 are waterproof pH/mV/ISE/Temperature Meters with automatic temperature compensation, which can measure pH, mV, ISE, temperature.

This manual introduces the use and precautions of HI981402C pH online monitor.

This document is an instruction manual for the HI 981402 online waterproof pH meter with alarm. The manual provides information on the warranty, usage instructions, maintenance requirements, and contact information for the product.

This document provides specifications and features of the PICCOLO® series pH testers. The series includes PICCOLO®, PICCOLO®2, and PICCOLO® plus ATC pH testers. They have different measurement ranges and temperature compensation capabilities, and are calibrated manually with automatic temperature compensation. Each model comes with pH electrode, buffer sachets, calibration screwdriver, and rugged carrying case.

The HI 9811-0 and HI 9811-5 are complete, versatile, rainproof portable combined meters designed with utmost precision and simplicity. Both models provide measurements for pH, EC and TDS ranges, which are easily selectable through a membrane keyboard on the front panel. Conductivity measurements are automatically compensated for tem- perature changes with a built-in temperature sensor. The temperature coefficient is fixed at 2%/°C. HI 9811-0 is a pH/EC/TDS meter designed for simplicity of use in taking pH, µS/cm and mg/L measurements. Suited for hydroponics, greenhouses, aquaculture, food and beverage industries.

pHep® HI 98107 Pocket-sized pH Meter is a rugged pH tester with replaceable electrode and renewable reference junction. The instrument can be calibrated at two points by the user, simply acting on the offset and slope calibration trimmers. pHep® is in compliance with the CE directives.
