揚げ物調理に使用して劣化した食用油の廃油時期(酸価値2.5～3.0)の目安を判断する為の試験紙です。 調理後のまだ熱い油に先端を浸けるだけなので、簡単に使えます。 油の捨て時がわかりやすい!紙が紫から緑に替わると捨て時です。 簡単にわかりやすいのでアルバイトの方や新人さんでも判断できます。 厚生労働省の「弁当及びそうざいの衛生規範について」(環食第161号、昭和54年)の通知では、「揚げ調理中の油脂が発煙点170℃未満、酸価値2.5超、カルボニル値50超で明らかに劣化していたら、そのすべてを新しい油脂と交換すること」としています。

酸価測定の公定法である酸・アルカリ滴定法の原理に基づいてpH指示薬、塩基性物質を濾紙に含浸し、乾燥させた試験紙です。 フライ油(加熱油脂)など、現場の品質管理に適しています。 判定時間(測定所要時間)は極めて短く、約30秒となっています。 判定操作はごく簡単で、誰にでも判定を行うことができます。 従来の酸価測定キットと異なり、溶剤を使用していないため、火気を特に意識することなく使用することができ、また、使用済みの試験紙は償却が可能です。

Description。USB-C is fantastic. What makes this cable even better is that one of the features we love so much about USB-C has been replicated to the USB-A 2.0 plug! These cables have minor， yet genius modifications that allow them to be plugged into their ports regardless of orientation. No longer will you fight the USB "super position" where both orientations of your plug seem incorrect. A simple solution to a problem that nearly everyone has faced.。Until we have converted all our hubs， chargers， and ports over to USB-C this is the cable you're going to need for basic USB 2.0 connections. This cable is much thinner and flexible than its 3.1 counterpart and is perfect for USB to serial applications as well as for direct connection to basic microcontrollers.。This cable has the D+/D- wires along side large-gauge VBUS/GND wires. Rated for 2A， we've successfully pulled 2A@5V with minimal voltage drop. If you're looking for a the full USB-C implementation checkout our USB 3.1 cable.。Features。Reversible USB-A connector。Reversible USB-C connector

油の劣化具合を4段階の「酸価」で表示する試験紙です。

使用している油脂、サラダ油など、常温で液体の食用植物油の過酸化物価を直接検査できます。 製品の製造段階でのチェック、流通状況の把握に非常に有効です。 油脂または抽出油脂分に試験紙を浸漬し、その呈色程度からPOVを判定します。 全操作時間は約4分間の簡易測定です。

TBA法により、油脂含有食品の劣化の程度を調べる、試験紙です。TBA(Thiobarbituric Acid)が油脂の劣化生成物と反応して、赤色色素を生じます。TBA法は、乳製品、バター、チーズ、魚肉、畜産物、クッキーなど、いろいろの油脂含有食品の劣化の程度をみる指標として、食品の分野で広くもちいられています。測定の際は、試験紙に水蒸気を当てて2分間の加熱が必要です。

必要な長さにカットして使えるロールタイプのpH試験紙です。 試験紙を試験液に漬けると、試験紙の色が変わります。変わった色をケースの標準色と比較することで、試験液のpH値がわかります。 カッティングエッジ付き。

水や土壌に含まれるオイルの有無を検出します。 炭化水素やガソリン、潤滑油と反応すると青色試験紙は濃青色に変色します。

Description。The SparkFun BME280 Atmospheric Sensor Breakout is the easy way to measure barometric pressure， humidity， and temperature readings all without taking up too much space. Basically， anything you need to know about atmospheric conditions you can find out from this tiny breakout. The BME280 Breakout has been design to be used in indoor/outdoor navigation， weather forecasting， home automation， and even personal health and wellness monitoring.。The on-board BME280 sensor measures atmospheric pressure from 30kPa to 110kPa as well as relative humidity and temperature. The breakout provides a 3.3V SPI interface， a 5V tolerant I2C interface(with pull-up resistors to 3.3V)， takes measurements at less than 1mA and idles less than 5μA. The BME280 Breakout board has 10 pins， but no more than six are used at a single time. The left side of the board provide power， ground， and I2C pins. The remaining pins which provide SPI functionality and have another power and ground， are broken out on the other side.。Note：The breakout does NOT have headers installed and will need to purchased and soldered on yourself. Check the。Recommended Products。section below for the type of headers we use in the Hookup Guide!。Features。Operation Voltage：3.3V。I2C SPI Communications Interface。Temp Range：-40C to 85C。Humidity Range：0 - 100% RH， =-3% from 20-80%。Pressure Range：30，000Pa to 110，000Pa， relative accuracy of 12Pa， absolute accuracy of 100Pa。Altitude Range：0 to 30，000 ft(9.2 km)， relative accuracy of 3.3 ft(1 m)at sea level， 6.6(2 m)at 30，000 ft.。Incredibly Small

Description。The PicoBuck LED Driver is an economical and easy to use driver that will allow you to control and blend three different LEDs on three different channels. By default， each channel is driven at 330mA； that current can be reduced by either presenting an analog voltage or a PWM signal to the board. Version 12 of the board adds a solderable jumper that can be closed to increase the maximum current to 660mA. The new voltage regulator also increased the voltage rating on the various components on the board， allowing it to be used up to the full 36V rating of the AL8805 part.。Three signal inputs are provided for dimming control. You can use the PWM signal from an Arduino or your favorite microcontroller to dim each channel individually， or you can tie them all to the same PWM for simultaneous dimming. Dimming can be done by an analog voltage(20%-100% of max current by varying voltage from .5V-2.5V)or by PWM(so long as PWM minimum voltage is less than .4V and maximum voltage is more than 2.4V)for a full 0-100% range. A small jumper is provided for each channel to allow you to increase the drive strength from 330mA to 660mA. Two mounting holes for 4-40 or M3 screws are provided on either side of the board. They are perforated so they can be easily snapped off with a pair of pliers， if a smaller footprint is desired.。Note：。If you're going to use screw terminals， this board uses two different sizes. Check the related products for both sizes you'll need.。Note：。The PicoBuck LED Driver was made in collaboration with Ethan Zonca. A portion of each sale is given back to him.

Description。Your 5V system can wield great power with this big， beefy relay board. How does 10A on the NC contacts and 20A on the NO contacts at 220VAC sound? The SparkFun Beefcake Relay Control Kit contains all the parts you need to get your high-power load under control. Only minimal assembly is required!。The heart of the board is sealed， SPDT 20A/10A Relay. The relay is controlled by 5V logic through transistor， and an LED tells you when the relay is closed. This is kit， so it comes as through-hole parts with assembly required， which makes for some nice soldering practice. Screw terminal connectors on either side of the board make it easy to incorporate into your project.。There are some pretty beefy traces connecting the relay to the load pins， but the 3-pin terminals are only rated for 15A max! If you plan on connecting larger load， you'll need to solder directly to the board. As always with high current and voltage， play it safe and use your judgment when deciding how much of load you want to put on board -- in open airflow the PCB can handle the full 20A for few minutes at time， but in an enclosed area heat can build up.。Note：Please keep in mind that this board is really meant for someone with experience and good knowledge of electricity. If you're uncomfortable soldering or dealing with high voltage， please check out the IoT Power Relay. The IoT Power Relay is fully enclosed， making it lot safer.。Get Started With the Beefcake Hookup Assembly Guide。Features。Voltage Rating：220VAC/28VDC。VCC requirements：4-6V， 150mA capable。SPDT pins exposed(Form C)。14 AWG screw terminals for relay connections.。10 AWG solder lugs for relay connections.。Flyback diode included。Zener recovery diode included(decreases turn-off time)。Heavy oz. copper on PCB
