Brief introduction

The RB-401D portable COD, ammonia nitrogen, total phosphorus, and total nitrogen measuring instrument is developed and designed by our company according to relevant standards; An integrated machine used by environmental monitoring and supervision personnel for on-site measurement of COD, ammonia nitrogen, total phosphorus, and total nitrogen content in water samples, suitable for outdoor on-site measurement.

This instrument is equipped with two large capacity lithium batteries, which can be used for pre-treatment digestion and water sample determination respectively. They do not interfere with each other and can be used for both AC and DC; Built in printer, real-time printing of measurement values, convenient for on-site analysis and discussion; Human computer interactive operation, simple operation, users can apply this product without complex professional knowledge.
