Product Description
The HI97750 Potassium LR and MR Portable Photometer Meter is an advanced laboratory and field instrument engineered for the precise quantification of potassium in water. With the capability to measure low and medium ranges (0.0–20.0 mg/L & 10–100 mg/L as elemental potassium), this device is ideal for use in agriculture, greenhouse soil monitoring, water quality analysis, and horticulture applications requiring high-quality potassium monitoring.
Equipped with a reference detector and a narrow band interference filter using a 466 nm LED, the HI97750 offers fast, repeatable measurements and ensures laboratory-grade accuracy. The unit features a user-friendly, high-resolution 128 x 64 pixel LCD with backlight, practical for all lighting conditions.
- Wide detection range: 0.0–20.0 mg/L and 10–100 mg/L (as K), with 0.1 mg/L resolution.
- Potassium accuracy: ±3 mg/L ±7% of reading at 25°C (for 0–20 mg/L), ±10 mg/L ±7% at 25°C (for 10–100 mg/L).
- Measurement method: Adaptation of the Turbidimetric Tetraphenylborate Method.
- Reference detector and bandpass filter (466 nm, 8 nm bandwidth) for reliable reading stability.
- Environment: IP67 water-resistant housing, suitable for 0–50°C / 0–100% RH operation.
- Automatic shut-off after 15 minutes (30 min pre-measurement) to save power.
- Logging memory stores 50 readings with GLP support.
- Battery Type/Life: 3 × 1.5V AA, over 800 measurements without backlight.
- Easy-to-use interface includes tutorial and CAL Check verification modes for confident, reproducible analysis.
Applications include laboratory water quality testing, environmental monitoring, greenhouse and agricultural management, and fertilizer solution analysis. Package contains one photometer meter (reagents not included), a round 24.6 mm diameter cuvette, and batteries. Compact and robust, the HI97750 is a reliable analytical tool for precise potassium determination in demanding settings.
