- Mounting / Environment: Portable
- Display Type: Digital Display
- User Controls: Digital Front Panel, Computer Interface
Description: swings, hydrogen sulfide, wastewater chemicals, heavy metals, or organic build-up on the sensor. Warm-up time is unnecessary so the analyzer can start measuring within 30 seconds of when it’s turned on. Simple Installation & Maintenance. The HACH LDO probe can be installed with a choice
Supplier: Analytical Technology, Inc.
Description: sample flows into a special chamber where the hydrogen sulfide is stripped from the sample. A sensor located in the gas stream measures the released H2S concentration and displays the results in terms of equivalent sulfide ion concentration in mg/l. Because sulfide measurements are often made

OPTISENS MAC 100
is suitable for the measurement of such different analytical parameters as pH/oxygen reduction potential (ORP), free chlorine, chlorine dioxide, ozone, hydrogen peroxide, conductive conductivity, inductive conductivity, and dissolved oxygen. Regardless of which sensor is used or which parameter is being measured, the device offers standardized startup and operation. The user can also opt to measure two different parameters or to connect two different sensors to one signal converter. This eliminates... (read more)
