PHB-1/PHB-4 Handheld pH Meter with Automatic Temperature Compensation 0.01 Accuracy Portable Digital pH Tester for Water 2

1.NOTE: Power Supply: Uses 4 AAA batteries. Batteries not included due to shipping restrictions; please prepare locally. Measurement Ranges: pH: 0.0 – 14.0 mV: ±1999mV Model Differences: PHB-1: Without temperature electrode, supports manual compensation (0–80°C). PHB-4: Comes with temperature electrode, supports manual/automatic compensation (0–80°C). Electrode Configuration: Default: Composite electrode (temp. compensation range: 0–40°C). To enable full 0–80°C compensation, a glass electrode is required (not included by default). Warranty Reminder: Glass electrodes are fragile and not covered under warranty if broken (except for damage during shipping). Due to page limitations, some configurations may not be listed.
