Product Manual

The Milwaukee Conductivity Pen is designed for hydroponic and other growers to help you make sure that your plants are receiving the right amount of nutrients. Keep EC in your target range to help you achieve better results.

Design Features

  • Measures conductivity and temperature with automatic temperature compensation.
  • An ideal range for hydroponics (0.00 to 10.00 mS/cm).
  • Units in mS/cm are easily convertible to ppm.
  • Factory calibrated with the ability to recalibrate if needed.
  • Replaceable electrode.
  • Fully waterproof to IP65.
  • 250 hours continuous use (3 x 1.5V batteries included).

Care and Use

Maintenance

EC electrodes can develop nutrient buildup over time. To minimize build-up, rinse the probe in fresh tap water after every use.

Converting EC to TDS

The Milwaukee EC Pen, like all conductivity meters, provides a measure of electrically charged ions in a solution and is an absolute measure of conductivity.

EC is often converted to TDS in parts per million (ppm). Different scales include the 500 scale, the 650 scale, and the 700 scale. However, true PPM can only be determined through chemical analysis.

Your mS/cm reading can be approximately converted to TDS (ppm), as shown in the examples below.

2.00 mS/cm = 2000 uS/cm = 1000 ppm on .50 factor scale
2.00 mS/cm = 2000 uS/cm = 1400 ppm on the 442 scale or .70 factor scale

We ship daily from Monday through Friday, and shipments are processed within 24-48 hours of cleared payment.
Orders placed over the weekend are processed on the next business day.

Shipping Rates

Shipping rates are calculated during checkout based on the weight, dimensions, and destination of the ordered items. We do our best to calculate the exact cost.

Updated 5/1/2023:

Please note that due to the higher shipping costs and larger dimensions of some of our products, our shipping calculator may not always provide an accurate shipping estimate. In these cases, we will reach out to you with an updated shipping quote after you place your order. If you have any questions about shipping costs, please don't hesitate to contact us before placing your order. We apologize for any inconvenience and appreciate your understanding.

Seres reserves the right to notify you of any additional shipping charges. We partner with multiple vendors and locations, which can alter shipping rates. In addition, there are conditions out of our control (rural areas, fuel surcharge, multiple shipments). If this occurs, you will be contacted immediately and have the right to modify or cancel your order for a full refund. 

Address Change / Order Cancellation

If you need to change the shipping address, please get in touch with us at support@seresag.com or call 1-877-237-3754

Once the order is shipped, we will do our best to perform an address intercept. You will be charged an Intercept Fee imposed by the shipping carrier. This fee varies from each carrier. Please note not all shipping carriers will accept address intercept changes.

If an order is canceled in transit, you are solely responsible for all shipping charges incurred by the Shipping Carrier.

Shipping charges will not be refunded.

Tracking

Once an order has been shipped, we will send an email and text message on file with the tracking number. If your order is fulfilled from multiple vendors or locations, you will receive shipment confirmations with tracking for each shipment. 

In addition, you can check the status of your order through the order confirmation email or within your profile page under Track Order.

Freight (LTL)

Scheduled appointments deliver freight shipments. You are responsible for inspecting for damage incurred in transit and signing before the driver leaves. DO NOT accept the shipment if there is any damage. If your freight shipment arrives damaged, contact us immediately.

Once delivered, we cannot reimburse paid freight charges or refund products.

Some restrictions may apply; Hawaii and Alaska do not qualify for free shipping offers.

Damaged Shipment

It rarely happens, but once in a while, products are damaged during Shipping. Therefore, please scrutinize all shipments for damaged or missing items before signing for them (if required).

The shipping carrier is responsible for items damaged during Shipping, which will most often be UPS, FedEx, or USPS. 

If assistance is needed, please get in touch with us immediately. Seres cannot promise refunds or replacements if this is not done within 72 hours. 

By signing your name and accepting shipment for a Freight(LTL) order, you get no reimbursement of freight charges, order costs, or any other charges incurred.

Lead Times

Please note that there is up to a 7-day processing period for orders containing Hawthorne products.

Signature

Due to the valuable contents of many products we sell,  the carrier may need a signature upon delivery. Please understand that this is a measure our company took to ensure safe delivery and fraud protection.

Third-Party Carriers will attempt to deliver a signature-required order three times. 

Please follow up with the carrier for assistance if a missed-delivery note is received.

If assistance is needed, please get in touch with us, so we can help contact the carrier. 

Shipping costs will not be refunded for missed shipments.


Seres is not responsible for any missing, lost, or stolen items.
 

At this time, we do not ship to post office boxes or APO/FPO addresses.
