Hanna Instruments – HI9810392 HALO2 Chocolate pH Testers with Bluetooth

The HALO2 pH Tester is a pocket-sized, Bluetooth-enabled meter designed for accurate, application-specific pH measurements in challenging environments. Its PVDF body with conical low-temperature glass tip ensures durability and precision, while the open junction with double Ag/AgCl reference provides fast, stable readings. Automatic or manual temperature compensation eliminates errors, and the IP65 casing protects against dust and water jets, making it suitable for lab or field use. With easy one-button operation, GLP compliance, and wireless connectivity, HALO2 integrates seamlessly into laboratory workflows.

  • Durable PVDF Electrode: Conical low-temperature glass tip, open junction, double Ag/AgCl reference
  • Automatic/Manual Temperature Compensation: Ensures accurate readings across temperatures
  • Wireless & GLP Ready: Bluetooth® connectivity for LIMS integration and compliance
  • Portable & IP65 Rated: Pocket-sized, water- and dust-resistant for field use

Description

The HALO2 pH Tester is engineered for precision pH measurement in diverse applications, from food and beverage to laboratory testing. It features a conical PVDF electrode with refillable gel electrolyte, allowing accurate and repeatable readings across 0–12 pH (–2.00 to 16.00 display range) with ±0.05 pH accuracy. Automatic or manual temperature compensation further enhances reliability, while the membrane tip and open junction optimize electrode response in challenging samples such as chocolate, dairy, and other viscous media.

HALO2 is designed for ease of use and integration, with a single-button operation, large readable LCD, and pocket-friendly design. The device includes cleaning and storage solutions to maintain electrode performance, and calibration is simplified using Hanna buffer sachets. Bluetooth connectivity allows seamless data transfer to laboratory information systems (LIMS), and GLP compliance ensures traceable measurements. Its IP65-rated casing guarantees continued operation even in dusty or wet environments, making it ideal for on-the-go testing and laboratory applications.
