"Pressure canners make it possible to preserve low-acid foods, and over time, the dial gauge
may become inaccurate and need calibration," said Laura Barr, a University of Illinois Extension nutrition and wellness educator.
The joint distortion values [gamma] (Figure 8) were based on the average of dial gauge
measurements in the joint region (Bertero, Popov, and Tang 1974), as indicated by the expression
Today's pressure canner may have a dial gauge
for indicating the pressure or a weighted gauge, for indicating and regulating the pressure.
The instrumentation for proposed technique requires two perspex plates bolted with two steel angle pieces separately, two dial gauges
with stand and a fixed reference platform for dial gauge
Model ME1C has full fluoropolymer flowpath and comes with optional vent control valve with dial gauge
, enabling variable fine adjustment of pumping speed.
These methods include pressure profiles (NCR strips), staining (copper sulfate), micrometer/depth dial gauge
, roll impressions, noncontact measurement, and IPC/McMahon abrasiveness.
An optional vent control valve with dial gauge
enables variable fine adjustment of the pumping speed.
