HI-991001 is a durable, portable, pH and temperature meter used for most pH measurements encountered in manufacturing and environmental testing protocols.

The meter is provided with a very rugged titanium bodied electrode with built-in temperature sensor for temperature compensated pH and temperature readings. It also contains an integral pH sensor pre-amplifier to provide stable measurements in electrically noisy environments.

Main features:

• Simultaneous pH and temperature measurements on a large dual-line LCD display
• Automatic pH calibration at one or two points within two memorised buffer sets (standard or NIST)
• Selectable temperature unit (°C)
• Electrode condition indicator
• mV of pH measurement for electrode check
• HI-12963 dedicated pH with integral temperature sensor
• Probe quick connect system
• Battery life indication and low battery detection
• Keystroke confirmation tone
• Auto-off function
• Waterproof casing IP67

Each meter is supplied complete with:

• HI-12963 pH/temperature probe with titanium body and DIN connector with 1m cable
• pH 4.01 & 7.01 buffer sachet
• HI-700601 General electrode cleaning solution (2 sachets)
• 100mL beaker
• Alkaline batteries: 1.5V AAA x3
• Rugged carrying case
• Calibration certificate of meter
• Calibration certificate of probe
• Instruction manual
