For smelting applications requiring an interference-resistant HCN sensor configuration, select this MH2000-HCN High Precision hydrogen cyanide detector. It combines electrochemical sensing with internal pump sampling and is offered in 0-10, 0-50 or 0-100 ppm versions.
Smelting Configuration and Range Selection
This is the High Precision configuration for smelting, with interference resistance as a sensor feature. Select it by application and sensor configuration, then choose the upper measuring limit needed by the measurement procedure.
All three ranges begin at zero. The chosen span identifies one order version. Although the Standard HCN product offers the same three spans, this link identifies the dedicated smelting configuration. Include that configuration name when specifying the instrument for purchase.

Sampling Arrangement and Instrument Setup
Ten suction levels adjust the internal pump, with flow up to 1 L/min. The instrument operating limits are -20°C to 50°C and 0-95% RH under non-condensing conditions. Plan the sampling arrangement around those instrument operating conditions.
An LCD dot-matrix display presents gas concentration, gas identity, unit, battery level and time. English and Chinese interfaces are supported, with selectable concentration units. Two-stage sound and light alarms use adjustable setpoints, and vibration is also available as an alarm output.
Self-check, zero calibration, factory reset and temperature and pressure compensation are available for setup. Follow the supplied instructions for the selected HCN configuration and the intended measurement procedure when using these controls.
Recording and Package
Optional recording supports more than 100,000 readings and an adjustable 5-3600 second interval. Specify optional USB download and printing requirements when ordering. The standard package includes the instrument, carrying case, charging/data cable and instruction manual.
Gallery views show the shared pump-detector housing; displayed readings are illustrative. The package contains one detector; recording is supplied only when selected as an optional function.

My first impression after opening and installing batteries was that this meter is very well built considering the price and manufacturer. I had read some reviews stating that it's amp measurements were not accurate below 5 amps, I haven't seen any issues in any measurements I've taken, even side by side with my fluke meters. I've successfully taken accurate amp, voltage and continuity measurements with this ETCR6920B, the display is nice and legible. I haven't tried storing data and making transfers to a PC yet, the soft case is good enough for storage on a shelf and the test leads are of good quality and rated for 1000v. There's nothing bad to say about this meter especially when you consider the price, it's a really great meter.
Works as described.
