Condition: used, This listing is for a Hanna HI 93728 Nitrate-Nitrogen Photometer. The unit is in full working condition and is ready for immediate release. Overview of Nitrates and Measurement Importance Nitrates are naturally occurring compounds produced from the decomposition of organic matter or from fertilizers. However, they can be converted to nitrites, which pose health risks. Guidelines for Nitrate Levels: Global Maximum: 45 mg/L for nitrates in water. Europe: 50 mg/L for potable water. Dodpfjxxyimex Acnock USA (EPA): 10 mg/L for nitrate nitrogen (NO₃-N), which equates to 45 mg/L of nitrates. HANNA® HI 93728 and HI 93828 Meters These handheld meters are designed for field measurements of nitrate levels with ease and accuracy. Key Features: HI 93728 Meter: Measures nitrogen nitrate from 0 to 30 mg/L (NO₃-N). To convert to nitrate concentration, multiply the reading by 4.43, allowing a maximum reading of up to 133 mg/L of nitrate (NO₃). Measurement Range: 0.0 to 30.0 mg/L (NO₃-N) Resolution: 0.1 mg/L Accuracy: ±0.5 mg/L ±10% of reading Light Source: LED at 555 nm Light Detection: Silicon Photocell Battery Type/Life: 1 x 9V with approximately 40 hours of continuous use. Operating Environment: 0 to 50°C (32 to 122°F); RH max 95% non-condensing Dimensions: 180 x 83 x 46 mm (7.1 x 3.3 x 1.8 inches) Weight: 290 g (10 oz.) Method: Adaptation of the cadmium reaction method, producing an amber tint in the sample upon reaction with nitrate-nitrogen.

Condition: used, This listing is for the Jenway 370 pH Meter The unit is in full working condition and is ready for immediate use Dsdpfxexv Ayco Acneck Key Features: Simple Operation: The Model 370 provides easy-to-use functionality, perfect for users who need consistent and reliable pH readings without complex setup. Its single pH input and manual temperature compensation make it quick to calibrate and use. Advanced Memory Function: The Model 370 includes a 32-reading non-volatile memory, which allows users to store measurements for later review or record-keeping. This feature is particularly valuable for users in need of precise documentation and traceability. Manual Temperature Compensation: Unlike automatic temperature compensation (ATC) in more advanced models, the Model 370 requires manual adjustment, making it ideal for users who are working in environments where temperature variations are minimal or predictable. Wide Measurement Range: The pH range of -2.00 to 16.00 and mV range of -1999 to +1999 offer versatility in various applications, while the temperature range of -10°C to +105°C (14°F to 221°F) ensures suitability for both laboratory and field conditions. Accuracy: The Model 370 is designed to provide accurate results, with ±0.02 pH, ±1 mV, and ±0.5°C tolerance, making it reliable for scientific measurements and testing. Durability and Design: With an IP65-rated splashproof design, the Model 370 is durable enough for use in harsh environments, offering protection against dust and water splashes
