HQ40d 雙通道數(shù)字化多參數(shù)測試儀
The HQ40d Dual-Input Digital Multi-Parameter Meter offers true Plug and Play operation with IntelliCAL™ pH, conductivity, and LDO® dissolved oxygen probes. Plug in any two IntelliCAL probes and get simultaneous measurement, simultaneous readout! "Smart" meters store probe serial numbers, calibration history, user ID, time, date and location of readings.

HQ40d可以同時顯示兩個參數(shù)。用戶可以在同一個樣品中測量不同的參數(shù)，也可以同時測量兩個樣品。探頭即插即用。帶有USB接口，通過USB適配器，可以傳輸數(shù)據(jù)到閃盤、電腦和打印機(jī)。標(biāo)配：戶外組件、4節(jié)5號電池、帶變壓器的電源線、CD光盤、USB適配器、操作手冊和快速啟動卡。HQ40d 650

技術(shù)規(guī)格一覽：
