LaMotte Sanitizer Strength Chlorine Test Strips

开关/计量表功能同样地作为通用，精确的压力开关连同压力表，利用时间证明差压表。可具有1或2个LED /光电晶体管驱动继电器。压力表读数不受开关操作。易于控制旋钮调整设定点。施加压力和开关的设置点是完全可见的。死区的宽度小于1％满量程为1指针。DPDT继电器可以很容易地联锁，以改变死区控制。正压，负压或差压低至0至300磅0.25”水柱满量程;设定点低.25 .01 WC“刻度单位。

The switch/gauges function in the same manner, as versatile, precise pressure switches combined with a pressure gauge utilizing the time proven magnehelic design. Available with 1 or 2 LED/phototransistor actuated relays. Gauge reading is unaffected by switch operation.Easy to adjust set points with knob controls. Apply pressure and switch set points are fully visible. Deadband is 1 pointer width—less than 1% full scale. DPDT relays can easily be interlocked to provide variable deadband control. For positive, negative or differential pressures as low as 0.25” water column to 0 to 300 psi full scale; set points as low as .01 w.c. on .25” scale unit.
