The HALO2 Wireless pH Tester is designed to bring simplicity and sophistication to pH testing in a variety of settings and environments.

• Open-source Bluetooth allows easy integration into current data logging systems
• IP65 water resistant protection
• Specialized electrode for spot checking pH
• Equipped with everything you need for successful testing right out of the box.

The HI98129 makes measuring pH quick and easy! This lightweight, waterproof tester offers high accuracy pH, low range EC/TDS (0 to 3999 µS/cm EC/ 0 to 2000 ppm TDS) and temperature measurements in a single handheld unit! No more switching between meters for your routine measurements.

• Waterproof
• Replaceable pH electrode with extractable junction
• Automatic calibration

The HI9813-61 is an economical, water resistant, portable meter that measures pH, conductivity (EC), total dissolved solids (TDS) and temperature with a single probe. The HI9813-61 features the Hanna Instruments CAL Check that will allow the user to know when the probe needs to be calibrated or replaced. The meter operation is simplified with dedicated buttons for measurement modes to be displayed on the LCD and knobs for single point calibration of pH and EC.

The HI9813-61 has a variable EC to TDS conversion factor that automatically changes from 0.56 to 0.78 ppm = 1 µS/cm based on the actual EC reading. This range is suitable for agricultural, greenhouse and hydroponic applications. The temperature correction coefficient (β) is fixed at 2%/°C.

Amplified pH electrode for immunity to electrical noise including from ballasts and pumps

Ph meter measures the acidity or alkalinity of a substance. They are commonly used for water testing and biological sample analysis in hydroponics aquaculture and agriculture. A portable meter is commonly used to measure the pH of substances such as food beer or wine and is also used to test cleaning water rinse water and wastewater in lab industrial and food applications.
