Hanna Hi9811-5 Portable Ph / Ec / Tds / °c MeterThe HI9811 5 is an economical, wateproof, portable meter that measures pH, conductivity (EC), total dissolved solids (TDS) and temperature (C) with a single probe. The meter operation is simplified with dedicated buttons for measurement modes to be be displayed on the LCD and knobs for single point calibration of pH and EC TDS. The HI9811 5 is most suitable for agricultural, greenhouse and hydroponic applications. The HI9811 5 portable meter features

The HI9811-5 is an economical, wateproof, portable meter that measures pH, conductivity (EC), total dissolved solids (TDS) and temperature (°C) with a single probe. The meter operation is simplified with dedicated buttons for measurement modes to be be displayed on the LCD and knobs for single point calibration of pH and EC/TDS. The HI9811-5 is most suitable for agricultural, greenhouse and hydroponic applications.

The HI9811-5 portable meter features a large LCD which displays either pH, EC, TDS or temperature readings along with tutorial instructions. The HI9811-5 is a simplistic pH/EC/TDS meter that is calibrated manually to a single point with the use of two trimmers. pH is calibrated to pH 7.01 while EC/TDS is calibrated to either 1.41 mS/cm (1413 µS/cm) or 1500 ppm. The LCD screen has battery life indicator as well as on-screen tutorial messages.

The supplied HI1285-5 probe is a polypropylene body, amplified pH electrode with a built-in EC/TDS and temperature sensors. The amplifier for the pH electrode prevents interference from humidity and electrical noise from common sources including from motors, ballasts or pumps. The HI9811-5 is a versatile meter best suited for agricultural, greenhouse and hydroponic applications.

HI1285-5 polypropylene body amplified pH electrode with built in EC/TDS and temperature sensors

The HI9811-5 is supplied with a polypropylene body pH/EC/TDS/temperature probe. The pH, EC, TDS, and temperature sensors are housed in a single body that connects to the meter with a DIN connector. This probe is specially engineered with a fiber junction and gel electrolyte to produce a fast response with reduced contamination.

Amplified pH electrode
The pH electrode circuit has a built in amplifier that will reduce the effects of electrical noise on the high impedance pH measurement. Examples of sources of electrical noise include motors, ballasts, and pumps which are common in greenhouses.

Amperometric EC/TDS sensor
The EC/TDS readings are performed by an amperometric sensor. An alternating voltage is applied to the sensor and the amount of current that passes between the two stainless steel pins is dependent upon the amount of salts (fertilizer) present. A greater amount of salt present results in an increase in conductance.

Polypropylene body
The polypropylene body houses all the sensors in a single body design and is durable. The probe is gel filled for maintenance free operation. It does not have to be refilled periodically.

3 sensors in a single probe
Pre-amplified pH electrode for resistance to electrical noise
Gel filled maintenance free pH electrode

Very good
Size: 1 Pound (Pack of 1)
There are two companies that have very little ingredients and this is one of them. I only buy dog treats that are made in the USA very little ingredients for a 1 pound bag so far this is the least expensive I need as small as I can get because I have a Golden and he doesn’t care whether he gets a tiny bit or 25 pound turkey. He wants more so the smaller they are the better it is for me. It must also be made in the USA and have very little ingredients right now. This is it.

Great fit and makes potty training easier
Size: 3T-4T, Unit Count: 84
These training pants have been a big help during potty training. They fit comfortably and feel soft against the skin, more like real underwear than a diaper. The stretchy sides make them easy for little ones to pull up and down on their own, which really helps with independence. They do a good job holding small accidents without leaking, and the fun character designs make my little one more excited to wear them. The pack comes with plenty to last through the training phase, which is nice when you’re going through a few each day. Tip: keep a few extras in the car or diaper bag for outings. It makes potty training on the go so much easier.

Great Pull-ups that Don't Leak!
Size: 3T-4T, Unit Count: 20
I was on the hunt for the perfect potty training pants for my little guy, and Pull-Ups Boys' Potty Training Pants in size 3T-4T turned out to be a great find. We’ve tried a few different brands, but these have been the most reliable. The design is fun and colorful, which my son loves, and it makes him excited to wear them. The fit is spot on for his size (32-40 lbs), and he moves around comfortably without any leaks. The absorbency is impressive – it gives me peace of mind knowing accidents won’t mean a complete outfit change. Overall, these Pull-Ups have made the potty training process a lot smoother for both of us. There are a few things to note, though. The price is a bit higher compared to some other brands, but I believe the quality justifies it. Also, while they are great during the day, we still need a bit more protection at night. I find myself using an extra layer for nighttime just to be safe. The packaging could also be improved – a resealable option would be nice to keep the remaining training pants fresh and organized. Despite these minor issues, I’m really happy with the product, and my son is well on his way to being fully potty trained. Pros: - Fun and colorful design that my son loves - Perfect fit for 32-40 lbs, allowing comfortable movement - Excellent absorbency, minimizing leaks - Helps make the potty training process smoother Cons: - Slightly higher price compared to other brands - Not as effective for overnight use, requiring additional protection - Packaging lacks a resealable option for convenience
