Etatron pH值水泵控制系统，20升/小时流量

Etatron pH Pump Control System, 20 L/hr Flow

一个完整的控制系统将控制器和变速计量泵结合为一体的设备！

方便的壁挂式外壳

最大压力为150 psi（10巴）

最大流量1.3 GPH（5升/小时）

控制系统很容易使用，只需通过前端安装设置旋钮输入您所需的pH值。控制器的响应对pH值的变化小于0.1个pH单位。比例输出机型自动冲程频率调整。系统开关可选送碱或送酸。开/关模式可调行程频率，一整圈控制旋钮来改变流量0到100％。

抽水频率成正比的输出模式，比例下降，直到它到达精确的设定点，我们的关键应用为您提供了更大的微调控制。当水槽液位太低时，比例输出控制模式液位开关可关闭抽水。订购控制液位开关07187-06 

防潮部件包括聚丙烯，聚四氟乙烯，Viton ®优异的耐化学性。环氧树脂涂层铝外壳耐腐蚀。清洁，密封垫的聚碳酸酯屏蔽罩的控制面板。手动排气除气液体泵头。控制系统接受BNC连接器电极没有温度补偿 

包含：一个6英尺长的透明PVC和PE管（3/16”ID×1/4” OD）和6英尺和弦（三三脚插头115VAC型;卷端头240 VAC模型。）

A complete control system-combines a controller and variable-speed metering pump all in one unit!

Convenient wall-mount housing

Maximum pressure 150 psi (10 bar)

Maximum flow rate 1.3 GPH (5 L/hr)

Control systems are easy to use-just enter your desired pH value via the front-mounted set knob. The controller responds to pH changes within 0.1 pH unit. Proportional output models feature automatic stroke frequency adjustment. Systems are switch-selectable for caustic or acid feed. On/off models feature adjustable stroke frequency to vary flow from 0 to 100% with one full turn of the control knob.

Pumping frequency in proportional output models decreases proportionally until it reaches the exact set point- gives you greater fine-tune control in our critical applications. Proportional output control models accept a level switch to shut down the pump when the liquid level in your tank is too low. Order level switch 07187-06 for control.

Wetted parts consist of polypropylene, PTFE, and Viton®for excellent chemical resistance. Epoxy-coated aluminum housing resists corrosion. Clear, gasketed, polycarbonate shield covers control panel. Manual air bleed pump head for outgassing fluids. Control systems accept electrodes with BNC connectors with no temperature compensation. 

What’s Included:

a 6-ft length of both clear PVC and PE tubing (3/16” ID x 1/4” OD) and 6-ft chord (with three-prong plug for 115VAC models; stripped ends for 240 VAC models.)
