特點(diǎn)

三電極測(cè)量單元

采用三電極技術(shù)測(cè)量單元進(jìn)行消毒劑檢測(cè)。此測(cè)量單元不需要其它類型分析儀所必需的頻繁調(diào)零，大幅提高了重復(fù)性和穩(wěn)定性，而且明顯的減少了維護(hù)工作量。該技術(shù)被應(yīng)用在裸電極和膜電極中。

無(wú)需試劑檢測(cè)余氫這種內(nèi)部緩沖膜式傳感器不需要任何試劑就可檢測(cè)自由氯或總氯，包括pH 值變化的樣水。因?yàn)闊o(wú)化學(xué)試劑加入水中，檢測(cè)過(guò)的樣水可返回供水管線，或不加任何處理的排放。

FEATURES
Three electrode measuring cell
For disinfectant measurement, a three electrode technology measuring cell is used. This cell eliminates the need for the constant zero adjustment typical of other analyzers. Reliability and stability are vastly improved while maintenance is dramatically reduced. This technology is used in both the bare-electrode and membrane-type cells.

靈活配置

有兩種電子控制單元選擇:只測(cè)量消毒劑的單信號(hào)輸入，以及測(cè)量消毒劑和PH值或氟化物的雙信號(hào)輸入。另外，根據(jù)測(cè)量單元配置不同，單輸入和雙輸入都可以獲得樣水溫度信號(hào)。測(cè)量單元共有5 種不同配置:兩種是裸電極測(cè)量單元( Depolox@ 3 PLUS 測(cè)量單元和Depolox@ 5 測(cè)量單元) ;還有兩種為膜電極測(cè)量單元( Depolox@ 3 PLUS 膜測(cè)量單元和VariaSens™ 測(cè)量單元) ;以及一種Y型過(guò)流探頭組件，僅用于檢測(cè)氟。

Reagentless chlorine measurement
The internally buffered membrane-type sensor measures free or total chlorine without the need for reagents. This includes samples with varying pH. With no chemical addition, the sample can be added back to the supply or simply drained without concern for discharge restrictions.

水處理技術(shù)部的電子技術(shù)

分析儀外殼封裝等級(jí)為NEMA 4X ，可提供3 個(gè)隔離4-20mA輸出信號(hào)，消毒劑余量、溫度、pH{直或氟。還有一個(gè)報(bào)警繼電器以及RS-485通訊接口，還包括背光式的LED顯示器和六鍵鍵盤(pán)，鍵盤(pán)可用于各種操作，包括輸入信息、設(shè)定，校準(zhǔn)和診斷菜單。

Flexible arrangements
There are two electronic control configurations: a single input version for disinfectant only measurement and a dual-input version for disinfectant and pH or fluoride measurement. In addition, a sample temperature output signal is available from both the single and dual input arrangements, dependent on the choice of flow cell. There are a total of five flow cell configurations: two that incorporate the integral bare-electrode measuring cell (DEPOLOX 3 plus and DEPOLOX 5 flow cell); two that accommodate the membrane-type measuring
cell (DEPOLOX 3 plus membrane-type and VariaSens™ flow cell); and a simple Y-type flow-thru probe holder for fluoride only measurement.

選擇測(cè)量單元

為確保檢測(cè)信號(hào)穩(wěn)定并且有代表性，需要連續(xù)的流量。連續(xù)流量取決于測(cè)量單元，以及測(cè)量單元采用的檢測(cè)技術(shù)。

Choice of flow cell technology
To ensure a stable, representative measurement signal, a constant flow rate is required. This is provided by a choice of flow cells, dependant on the type of measurement technology that is used:

用于自由氫的裸電極測(cè)量單元

該檢測(cè)技術(shù)的特點(diǎn)是用于自由氯的裸電極測(cè)量單元。利用三電極單元，這種獨(dú)特的同時(shí)結(jié)合分析儀/傳感器的方式，具有非?？斓捻憫?yīng)時(shí)間(變化90%<20秒) ，以及很高的精度(滿量程的:t 2% ) ，以滿足波動(dòng)較大的消毒應(yīng)用，或者適合用在水質(zhì)硬度過(guò)大而無(wú)法使用膜電極的情況下。為維持裸電極傳感器的靈敏度，延長(zhǎng)校準(zhǔn)的時(shí)間間隔，可采用石英砂根據(jù)流體力學(xué)清潔電極表面，但要求樣水具有穩(wěn)定的pH 值。另一選擇是附加pH傳感器，利用雙輸入控制單元，無(wú)需加入緩沖試劑即可在測(cè)量自由氯時(shí)對(duì)pH 值進(jìn)行補(bǔ)償。

Bare-electrode type cell for free chlorine
This measurement technology features an integral, bare-electrode flow cell for free chlorine. Utilizing the three electrode cell design described above, this unique combination of analyzer/sensor provides a very quick response time (90% change < 20 sec.) with high accuracy (±2% F.S.) to meet fluctuating disinfection demands or applications where there is a high degree of hardness, which prohibits the use of a membrane-type sensor. The well-proven principle of hydromechanical grit cleaning of the electrode surfaces maintains the sensitivity of the bare-electrode sensors extending the interval time between calibrations. A sample with a constant pH is required.
Alternatively, the addition of a pH sensor, utilizing the dual input electronic package, provides for a pH-compensated free Cl2 measurement without the need to buffer the sample.

此經(jīng)濟(jì)的測(cè)量單元組合包括一個(gè)透明玻璃樹(shù)脂樣水杯，并帶有流量調(diào)節(jié)器以便為檢測(cè)電極提供連續(xù)的樣水流量。配有內(nèi)置的PT 100傳感器，在測(cè)量余氯的同時(shí)可提供溫度補(bǔ)償及溫度檢測(cè)輸出信號(hào)?？赏ㄟ^(guò)測(cè)量單元頂蓋增加pH 值或氟化物傳感器探頭。

An integral PT 100 sensor provides for temperature compensation of the chlorine residual reading as well as a temperature measurement output signal. An additional sensor probe for pH or Fluoride can be added through the flow cell cover.

膜電極測(cè)量單元

膜電極傳感器可檢測(cè)四種消毒劑指標(biāo):自由氯、總氯、二氧化氯或者臭氧。三電極檢測(cè)技術(shù)與膜相結(jié)合，可使這些氧化劑均勻擴(kuò)散到傳感器上。內(nèi)部緩沖試劑減少了pH{直對(duì)檢測(cè)余氯時(shí)的影響。因此，對(duì)于pH 值有變化的樣水，不需要進(jìn)行外部pH 緩沖或pH值補(bǔ)償。傳感器內(nèi)置余氯測(cè)量時(shí)的溫度補(bǔ)償。

Membrane-type cell
There are four disinfectant specific, membrane-type sensors available for measuring either free chlorine, total chlorine, chlorine dioxide, or ozone. Utilizing the three electrode measurement technology, these sensors incorporate a membrane for diffusion of the oxidant into the working electrode. An internal, buffered electrolyte reduces the effect of pH on chlorine measurement. Therefore, external pH buffering or pH compensation is not required
for samples with a varying pH. Temperature compensation of the chlorine residual reading is built into the sensor.

DEPOLOX 3 plus membrane - type flow cell
This simple flow block housing is designed to provide a constant flow of water past the membrane surface of the removable sensor. Sensors can easily be changed to monitor different disinfectants. A water jet, designed into the flow block, removes any bubbles from the membrane surface, which can affect accuracy and stability. An additional sensor probe for pH or Fluoride can be added through the flow cell cover. Note that a measured temperature output is not available with this flow cell.

VariaSens ™測(cè)量單元

此測(cè)量單元，在上述測(cè)量單元的基礎(chǔ)上，內(nèi)部集成了一個(gè)流量調(diào)節(jié)器可保持樣水流量恒定為33 I/h o 多功能傳感器為PT 1000 ，可提供溫度監(jiān)測(cè)和輸出以及監(jiān)測(cè)樣水流量，還可提供流量丟失報(bào)警信號(hào)。

In addition to the above, this flow block assembly utilizes an integral flow regulator to maintain the sample flow at a constant 33 l/h. An integral multi-sensor provides a PT 1000 temperature measurement and output and monitors sample flow to provide a loss-of-flow alarm contact.

僅檢測(cè)氟

如果氟化物是需要檢測(cè)的參數(shù)，則可以提供一個(gè)簡(jiǎn)單的過(guò)流裝置，其中包括一個(gè)Y型過(guò)流組件和一個(gè)樣水閥門(mén)。注意該配置中不包括溫度檢測(cè)和輸出。

Fluoride-Only Measurement
If fluoride is the only parameter to be measured, then a simple, flowthrough probe assembly can be provided. This consists of a Y-type flow-thru probe holder and a sample valve. Note that temperature measurement and output is not available with this configuration.
