    Digital Water Quality Tester TDS Meter With Thermometer (TDS-3)

    Digital Water Quality Tester TDS Meter With Thermometer (TDS-3)

    • Condition: New
    • The Digital TDS-3 handheld water quality tester enables you to determine just how good or bad your water really is!
    • These testers measure the TDS level in your water.
    • Ideal for testing reverse osmosis membrane performance and determining the need for replacement. Ideal for all water purification applications, wastewater regulation, aquaculture, hydroponics, and colloidal silver.
    • Perfect for both consumer or commercial use.
    • Carry one in your pocket or toolbox at all times!
    • Advanced microprocessor technology.
    • Hold function -- Saves measurements for convenient reading and recording, with the sound of a buzzer.
    • Auto-off function -- Turns off meter after 10 minutes of non-use to conserve batteries.
    • Automatic function -- After operating three minutes in the same condition, the measurement simply stops.
    • High TDS Reading -- In case of measuring over 999ppm, the figure of X 10 twinkles automatically.
    • Digital Thermometer -- Built-in thermometer with temp button.
    • Display -- Easy-to-read LCD screen.
    • Power by 2*LR44 Button battery (Included)
    • Factory Calibrated -- Recalibration is not necessary, but can be done easily with a watch screwdriver.
    • The NSF minimum Standard for Percent Rejection is 75%. We recommend replacing the RO membrane once it tests at 80% rejection or lower.

    Easy to Follow Instructions!

    • Using a clean cup or glass, take a sample of your raw feed water.
    • Remove the protective cap from the Tester.
    • Push the "ON" button to activate LCD display.
    • Submerse the tester's probes into the water sample and observe for approx. 10 seconds.
    • Record the results.
    • Repeat the same procedure with a sample of your reverse osmosis (RO) water.
    • If the system is new or the membrane has been replaced, do not test the first tank of RO water. The first tank of product water will contain sanitizer and possibly carbon fines from your new filters. This will cause false reading.
    • Use the formula as picture show to calculate the percentage of solids (TDS) that your membrane is removing:

    【应用范围】:

    纯净水生产和饮用、电渡液、锅炉用水、鱼缸用水、游泳池水的洁净度、照相冲洗液、井水,深井水、实验室、水产养殖、食品加工、家庭,办公室、理化教学、电离水 化妆品、市政供水、旅行保健

    【测试笔规格参数】:

    轻巧袖珍→重50克,为当今市场体积较小,重量较轻的便携式TDS测试笔仪器,长15.6×宽3×厚2(CM)。
    测量范围广→能够测量1-9990PPM。
    应用温度广→在0-80度工作,可在零下30度储藏。
    液晶显示窗→大屏幕液晶显示防水设计,方便观看经久耐用。
    电池寿命长→采用LR44 1.5V电池2粒,可使用3年以上,10分钟不操作自动关机功能,节省电池。
    设计合理→笔端电极可直接插入被测水溶液中测量,笔套还可以做为被测水溶液的容器来使用,极为方便。
    测量快速→由于精巧裸式的传感元件,5秒可完成一次测量。
    准确度高→±5%的误差,钛合金探针测水精度高,免受水中的磁干扰影响。
    自动温度补偿→可自动将示值换算成25度时的示值。
    【影响TDS值测试的因素产品使用说明】:

    水温:TDS笔不可用于测量高温水体(例如:热开水)
    水的流速:TDS笔不能用于测量晃动较大的水体

    【使用说明】:

    取下笔套,打开ON开关;
    将笔放入测试溶液中,溶液高度不得超2cm;
    将笔在溶液中搅动,待读数稳定(2-6秒)后,TDS数值将会显示在屏幕上,这时按HOLD键锁定数值。如果显示屏上闪烁“X10”的图样,读数须乘以10再读。
    使用完毕后擦干笔头上的水,用纯净水清洗干净,将笔套盖回即可。
    使用注意事项:避免将TDS笔全身浸泡到水中,避免阳光直射,远离高温,避免撞击重压和摔碰。

    【注意事项】:

    仪器不能防水,不要让液体超过浸没线。
    不可随意调校仪器,仪器在出厂前已经校正。
    如遇示值误差大,示值跳动,示值不归零等现象,应将仪器浸没线以下部位插入酒精中晃动几下,以清洗传感器.

    【电池更换】:

    若显示模糊或不显示,显示值误差大(用酒精清洗电极后),则应检查电池电压,低于2.5伏应及时更换电池。更换电池是拉出电池仓即可,注意电池极性。

     

    产品测试出来的TDS值比对表:

    中国制订的饮用水标准:

    ■ 自来水300PPM以下
    ■ 纯水50PPM以下
    ■ 矿泉水100-200PPM之间

    国际标准如下:

    ■ 蒸馏水(二次蒸馏):000 PPM
    ■ 高纯水:000 PPM
    ■饮用纯净水:000——00 1 PPM
    ■优质矿泉水:002——050 PPM

    水硬度GH值和TDS值之间的一般换算比例:

    0-89ppm(μs)→强软水0-4dh

    90-159ppm→软水5-8dh

    160-229ppm→适度硬水9-12dh

    230-339ppm→中度硬水13-18dh

    340-534ppm→硬水19-30dh

    大于535ppm→强硬水30dh以上

    使用注意:
    1、纯净水、矿泉水久置后,TDS值较开始时上升过高,共病毒和菌落总数也会相应增高,此时不可生饮,影响健康;
    2、纯酒精TDS值为0,大于0则表示不纯;
    3、TDS即总固体溶解量。如示值为100,即每升中含100毫克杂质;
    4、3楼以上的用户,由顶层蓄水箱供水,易造成二次污染,应常检测TDS值的变化,可催促物业管理部门定期清洗。
    5、洗衣机应放多少洗衣粉,用TDS笔检测可将经验数字化。清洗程序后,排水前检测的示值与自来水一样即可视为清洗干净,若示值超过自来水,则应减少洗衣粉的投入量;
    6、水果、蔬菜若用水浸泡,测其TDS值若有偏高,可怀疑有化学污染,应引起重视。
    7、去泳池游泳过程中可测池水清洁度的变化,示值过高应引起重视;
    8、深井水若示值高达300以上,说明杂质含量过高;
    9、每个地区,城市由于管道及水源不同,TDS值不同;
    10、北方硬水含钙镁离子,TDS值偏高,会结水垢;一般硬水150~400(结垢)。超硬水(若咸水)大于400(严重结垢)。
    11、花肥首次按规定配制后,测其值,用该数字可方便今后配制;
    12、金鱼缸用水,可测其值,知其洁净程度。若数值上长噎大,应及时换水;
    13、海产养殖用水,可测其值,以便今后配制和检测。
    注:本产品也适用于搞无土栽培,需要电导率仪测营养液离子含量。本产品能用于营养液浓度测量。测二次的数值相减即可。方法是先测一次自来水的TDS值,再加入营养液,测出其数值,二次相减的数值即为所求值。

    此笔可测水的硬度与纯度:
    tds超过40就不算是纯净水啦,
    一般乡下的井水都是在400以上,
    RO反渗透,五级过滤,不带软水功能的,
    TDS值一般要小于35,如果是带软水功能的,数值要更小。
    蒸馏水的TDS值一般要接近0
    纯净水它的TDS值一般要小于10,
    自来水要看各地区而不同的,一般在100-250之间。
    使用注意事项:避免将TDS笔浸泡到水里,避免直射光线和高温,避免撞击重压和摔落。
