HM Digital Hydromaster Portable - pH/TDS/EC/Temp

Portable pH/TDS/EC/Temp Monitor with Data Storage

A continuous in-line monitor works well for a fixed reservoir, but growers checking multiple systems need something they can carry between them. The HM Digital Hydromaster Portable (HM-200) is a handheld pH/TDS/EC/Temp monitor built to travel.

Sold as one HM Digital Hydromaster Portable meter, includes probes, calibration solutions, and protective boot.

Key Features & Benefits

• Portable handheld design — 1.2lb with a protective rubber boot, built to move between systems.
• Displays 3 parameters simultaneously — pH/EC or TDS/Temp shown together on a large LCD screen.
• Push-button calibration with automatic buffer recognition — simplifies calibrating against known standards.
• Stores and recalls up to 20 measurements — review recent readings without a separate log.
• Ships complete with probes and calibration solutions — pH and EC/TDS probes plus pH 4 & 7 solutions included.

Who Should Use the HM Digital Hydromaster HM-200

This fits growers managing multiple reservoirs or grow rooms who need one portable meter to carry between systems, rather than a fixed continuous monitor.

Yes, it has data storage and recall for up to 20 measurements. That history lets you compare recent readings without keeping a separate written log.

How portable is this meter?

It weighs 1.2 pounds and includes a protective rubber boot for handling between locations. That combination of weight and protection is built for carrying between multiple reservoirs or grow areas.
