Online Hardness Analyzer Selection Guide: How to Choose the Right Model Based on Application Scenarios

Selecting the right online hardness analyzer requires evaluating multiple factors. First, consider the measurement range: boiler feedwater typically requires 0-10 ppm, while cooling circulation water may need 0-50 ppm. Next, evaluate accuracy requirements; for high-precision applications like pharmaceutical manufacturing, choose a device with accuracy better than ±0.5% F.S. Additionally, account for installation conditions (temperature, humidity, IP rating), communication interfaces (4-20mA, RS485, Modbus), and whether explosion-proof certification is needed. LOHMET's full line of water analysis instruments supports multiple communication protocols and mounting options, allowing flexible configuration to meet your specific needs.
