Selected product option for Waterproof pH meter. All information below applies to the selected product option.
Routine pH checks in water applications should be quick, clear and reliable, without carrying more instrument than the job needs. ECO 510 covers the full pH range from 0.00 to 14.00 pH with ±0.02 pH ± 1 digit accuracy at 25 °C, giving technicians a compact handheld meter for pools, well-water, aquaristics, aquaculture, water monitoring, plant cultivation, laboratories and quality assurance.
For field work and wet environments, the housing is dust- and water-protected with ingress protection (IP65/IP67) when used with waterproof electrodes. A BNC connector accepts interchangeable pH electrodes, while the 3-line backlit LCD, hold function and min/max function keep readings easy to view and document. With 2 AA batteries and > 3000 h typical operation, it is built for long measuring days.
The ECO 510 measures pH in water and aqueous media using suitable BNC electrodes. The medium temperature can be entered manually for applications with stable temperature conditions.
ECO 511 includes a flexible temperature input for temperture probes or electrodes with integrated T-sensor. All compensations are done automatically.
The ECO 511 measures pH and redox with suitable electrodes. It supports ORP display in mV or mVH and includes automatic temperature compensation when a Pt1000 sensor is connected.
The device uses a 3-line LCD with battery status display, backlight and shatterproof glass. The display can be rotated for overhead viewing at the touch of a button.
Hold freezes the current measured value. Min/max functions show the lowest and highest recorded values and can be reset from the keypad.
Automatic pH calibration uses two GPH buffer solutions and compensates their temperature dependence. Manual 1-point and 2-point calibration are available.
The menu includes temperature unit selection, automatic switch-off, backlight timing and factory reset. ECO 511 also provides configurable alarm modes and limits.
The compact housing measures 108 x 54 x 28 mm, with an impact-resistant ABS body and polyester front panel. Weight is approx. 130 g for ECO 510 and approx. 135 g for ECO 511.
