Digital display online PH/ORP meter
Digital display online PH/ORP meters from Henan Greeenland Tech Industrial Co. Ltd are designed for continuous monitoring of acidity and oxidation-reduction potential in water treatment and industrial processes. These systems consist of a sensor, transmitter, and process fitting, calibrated to measure pH from 0 to 14 and ORP from -1999 to +1999mV. The display shows real-time values with temperature compensation, and outputs are available for control signals to dosing pumps or alarms.
The pH sensor is typically a combination electrode with a glass membrane and reference junction, suitable for use in clean water, wastewater, or mildly corrosive environments. ORP sensors use platinum or gold electrodes. Standard temperature sensors are Pt100 or thermistor-based, with compensation ranging from 0°C to 70°C. The transmitter housing is ABS or polycarbonate, rated IP65. The listing does not specify sensor type, but BOQU Instrument models commonly use refillable reference electrodes for longer service life.
These meters are used in municipal water plants, pharmaceutical production, aquaculture, and chemical processing where precise control of water chemistry is required. Buyers include water treatment engineers, plant operators, and OEMs integrating water quality systems. Trade terms are typically FOB Zhengzhou or CIF port, with packaging in sealed foam-lined boxes. Minimum order quantities and lead times are not disclosed and must be confirmed directly with the supplier.

Henan Greeenland Tech Industrial Co. Ltd is located in Zhengzhou, Henan Province, with a registered address in a commercial building. The company is classified as a harbor-trusted supplier, indicating verified export records and customs compliance. The listing shows no response rate or average response time, suggesting limited buyer interaction. No information is provided about production scale, certifications, or years of operation.
The company appears to market water quality instrumentation under the BOQU Instrument brand, likely sourcing or assembling meters from third-party components. There is no mention of in-house sensor manufacturing, calibration lab, or R&D team. The absence of technical documentation or client references indicates this is a trading or OEM supplier focused on volume export rather than technical differentiation.

Sourcing Digital display online PH/ORP meter from Henan Greeenland Tech Industrial Co. Ltd - China Import Guide
Before ordering, verify the sensor type, cable length, and output signal compatibility with your control system. Request a calibration certificate traceable to NIST or equivalent, and confirm the temperature compensation method. Check if the sensor is refillable or sealed, as this affects long-term maintenance costs. Do not assume default settings match your process conditions - configuration must be confirmed in writing.
Lead time is not stated; buyers should confirm if units are in stock or require production. Common Incoterms are FOB Zhengzhou or CIF port, but freight and insurance responsibilities must be clarified. Payment terms are typically 30% advance, 70% against copy of B/L. Confirm whether the supplier accepts LC or TT, and request a sample unit for functional testing before bulk shipment.
Upon receipt, inspect the sensor for cracks or dry membranes. Test the meter with fresh buffer solutions (pH 4.01 and 7.00) and verify output signal accuracy with a multimeter. Check for stable readings over 15 minutes and confirm alarm thresholds are programmable. Retain calibration records and packaging for warranty claims. Ensure the transmitter is mounted in a dry, shaded location away from electromagnetic interference.
