PH tester BK-Y series

nitrogensalinityK+

Overview
Brand: BIOBASE
Models: BK-Y6A, BK-Y6PC, BK-Y7PC
Origin: China · Delivery: within 7 days · Supply: factory direct
Purpose: Designed for rapid, on-site and laboratory measurement of available nitrogen (N), available phosphorus (P), available potassium (K), organic matter, soil pH and soil salinity in soil, plants and chemical fertilizers. BK-Y6PC adds PC connectivity for data transfer; BK-Y7PC (based on BK-Y6PC) adds soil moisture measurement.

Key features

• Clear LCD readout and integrated print function for test date, sample ID, parameters and variety.
• Large onboard storage for time, location and fertilizer records; stored data can be queried on device.
• Fast quantitative tests for N, P, K, organic matter, pH and salinity; optional soil moisture measurement (BK-Y7PC).
• Automatic time-stamp for each test and configurable crop variety/yield to calculate recommended fertilization amounts based on built-in crop database (73 crops).
• BK-Y6PC supports computer connection via supplied software for data storage, transmission and printing.

Technical specifications

• Measured parameters: Available N, available P, available K, organic matter, soil pH (1–14, ±0.5%), soil salinity (0.01%–1.00%, ±0.1%), moisture (BK-Y7PC: %(m3/m3), accuracy ±2%, range 0–100%).
• Optical performance: stability (light drift absorbance <0.003), repeatability (absorbance <0.005), linearity error <3.0% (red light for CuSO4, blue for K2Cr2O7).
• Wavelengths/sensitivity: Red 620±5 nm (≥4.5×10⁻⁵), Blue 440±5 nm (≥3.17×10⁻³).
• Functions: data storage, printing, built-in nutrient requirements for 73 crop types, fertilization guidance.
• Power: AC 110–240 V, 50/60 Hz · Packing size: 700×400×250 mm · Gross weight: 10 kg.

Applications
