Hanna Instruments HI122-01 pH/ORP/Temperature Benchtop Meter with Built-in Dot Matrix Printer

Product Description

Benchtop pH, oxygen reduction potential (ORP)/mV, and temperature meter with built-in printer used in laboratory applications

Manual temperature compensation, Automatic Temperature Compensation (ATC) for accurate readings in fluctuating temperatures, and five-point pH calibration with standard and custom pH buffers and calibration alerts

Multilevel LCD screen simultaneously shows the current measurement and the current temperature

Built-in impact printer prints the measured, set, or recorded data automatically or on demand in four languages

Automatic data-logging of up to 1000 records, log-on-demand of up to 50 samples, and RS-232 interface for data transfer

Imported from USA

The Hanna Instruments HI 122-01 is a benchtop pH, oxygen reduction potential (ORP)/mV, and temperature meter with
built-in printer with manual temperature compensation, Automatic Temperature Compensation (ATC), five-point pH
calibration, a multilevel LCD screen, a built-in printer, and automatic logging. A pH meter is commonly used to measure
the pH of substance such as water, food, beer, or wine in lab, industrial and food applications. An ORP meter, also
known as a redox potential tester, is used to measure the oxidization or reduction capacity of a solution, and to
monitor chemical reactions and ion activity. It is commonly used for water testing, pulp bleaching, and for biological
sample analysis in swimming pools, cooling towers, waste water treatment, and industrial applications. The multilevel
LCD screen simultaneously displays the current measurement and the current temperature. Graphics display electrode
condition and electrode response. A hold function freezes readings for recording. Log-on-demand stores up to 50 samples
and auto-logging stores up to 1000 samples for each input channel. The meter has an opto-isolated RS-232 serial port for
data transfer.

ATC is provided by the HI 7662-T temperature probe (included). The meter has up to five-point calibration with seven
memorized buffers (1.68, 4.01, 6.86, 7.01, 9.18, 10.01, and 12.45 pH) and two custom buffers. A calibration check
feature provides status of electrode condition and response time and status of the buffer solutions during calibration.
The meter comes with the HI 1131P glass body, ceramic single-junction pH electrode with a spheric tip, a Bayonet
Neill-Concelman (BNC) connector + pin connector, and a 1m (3.3') coaxial cable. The meter measures ORP/mV when using a
compatible ORP electrode (not included). The operating temperature is 0 to 50 degrees C (32 to 122 degrees F) with a
relative humidity of 95 percent. The input impedance is 10 E 12 Ohm. The meter power supply is 115V and it comes with a
12VDC adapter and weighs 500g/1.1lb.The HI 122-01 also comes with buffer solutions, electrolyte solution, paper rolls,
and instructions.

D is depth, the horizontal distance from front to back.

A pH meter, also called a sensor or tester, is a device used to measure the acidity or alkalinity of a substance. A pH
meter has either a portable or a benchtop body. Many portable meters are handheld devices. Some testers have an internal
sensor, and may have a tip and body that fit inside of a container for measurement. A meter is commonly used in many
different environments from laboratories to field research and manufacturing facilities. Researchers, manufacturers, and
hobbyists use a pH meter in aquaculture, agricultural, wine-making, and water-testing, and for scientific applications.
Some pH meters may measure additional parameters such as dissolved oxygen (DO), conductivity (also called
electro-conductivity or EC), temperature, total dissolved solids (TDS), salinity, resistivity, or oxygen reduction
potential (ORP)/mV.

Hanna Instruments manufactures analytical instrumentation and supplies, including pH meters, electrodes, chemical
reagents, and buffer solutions. The company, founded in 1978 and headquartered in Woonsocket, RI, meets International
Organization for Standardization (ISO) standard 9001.
