Hanna Potassium LR and MR Portable Photometer-Kit - HI97750C

Hanna HI97750C Portable Potassium LR and MR Photometer Kit is purpose-built for the accurate and rapid determination of potassium concentration in water samples across laboratory, greenhouse, agricultural, and horticultural settings. Utilizing an advanced optical system with a reference detector and 8 nm narrow band interference filters, the device ensures extremely fast and repeatable measurements without the need for warm-up time.

• The HI97750C photometer supports both low range (0.0–20.0 mg/L as K) and medium range (10–100 mg/L as K) measurements, with a high level of precision and accuracy (±3 mg/L or ±7% of reading at 25°C for LR, ±10 mg/L or ±7% at 25°C for MR).
• Designed for user convenience, the photometer includes a large, backlit LCD display and an intuitive tutorial mode providing step-by-step operational guidance.
• The innovative CAL Check feature enhances data reliability by letting users verify the instrument’s calibration and performance at any time.
• The logging memory can store up to 50 readings, making data management efficient.
• Powered by three 1.5 V AA alkaline batteries, the instrument can perform over 800 measurements per charge (without backlight use), and features an automatic shut-off after 15 minutes of inactivity.
• The rugged housing (IP67 rated) enables reliable operation in laboratory and challenging field conditions (0 to 50°C, up to 100% relative humidity).
• Cuvette design: round type, 24.6 mm diameter (22 mm inner), with silicon photocell light detector and LED light source at 466 nm bandpass.
• The kit is ideal for environmental analysis, greenhouse crop management, water quality control in agriculture, and fertilizer assessment.
• Set includes photometer, sample cuvettes, calibration standards, batteries, and user manual—making it ready for immediate portable use.

This HI97750C unit is preferred for demanding agricultural, horticultural, and industrial laboratory applications requiring precise potassium measurement. For more laboratory photometers and technical solutions, explore the EnvMart category for Hanna and advanced photometry instruments.
