Waterproof housing and simple calibration bring reassurance for anyone who needs reliable field readings. Is the HM Digital PH-200 PH Meter accurate and durable enough for routine monitoring?
⚡ At a Glance
- • Measurement Range: 0-14 pH, 0-80 °C (32-176 °F)
- • Best for: Gardeners, aquarists and tradespeople needing quick on-site checks
- • Not ideal for: Users who require traceable laboratory certification or advanced analytics
Handheld meter covers the full pH scale and a wide temperature range. Compact size suits quick spot checks around the home and on site.
Consistent, repeatable readings - thanks to autoranging three-point calibration
Autoranging three-point calibration with digital fine-tuning adjusts sensor response across the full pH scale and lets the electrode be aligned to standard buffer solutions. The digital adjustment refines calibration points for closer agreement between readings.
Routine calibration yields more reliable measurements for ongoing maintenance tasks such as pond care, soil testing and aquarium checks.
Durable for field work - with waterproof IP-67 housing
IP-67-rated housing seals electronics against dust and water ingress, protecting internal components during damp or splashed conditions. Sealed controls and casing reduce the risk of moisture-related failure.
Robust construction reduces worry when testing around ponds, outdoor beds and wet work environments, making the meter suited to everyday outdoor use.
Portable and easy to carry - with compact handheld dimensions
Handheld dimensions of approximately 3.3" x 8.5" x 2" keep the meter small enough for a jacket pocket or toolkit while retaining a usable keypad and display. The form factor balances handheld comfort with practical visibility.
Compact size makes it simple to carry between sites and store when not required, encouraging more frequent spot checks without bulky kit.
